when i built it my units didnt upgrade, i this because they werent in the city when it was finished? i had archers and i think catapults but they didnt change at all. can someone explain it better?

If you do not have cannon/artillery technology your catapults are upgraded to catapults.

i.e. You must have something better for them to turn into.
Archers will upgrade to pikemen/riflemen/modern infantry but only if you have one of those technologies.

I always save Leonardo's until I have artillery/tanks/modern infantry.

It makes no difference if they are in a town or not.

aye make sure you have the techs needed to upgrade your units, they will all be updated to your highest tech not simply to their next level

techs techs

I found that archers tend not to upgrade into Rifleman unless you could build pikemen as well. So if you get Leonardos Workshop after Gunpowder but before Democracy they won't upgrade. Not sure if this happens with other strands of units.

I tried some game will upgrade, some does not.
Both the rifleman has up, but it does not work.
Need more Bro. input badly......

I've had the same thing happening to me too, although I had metallurgy and gunpowder. I think it's a rare bug, mate...

This is what I found about Leonardo's Workshop.

1. The upgrade takes place only ONE time, right after you build it.

2. You MUST have the pre-requisite tech for the next tier unit in which to upgrade your old units to.

3. The upgrade is only one tier up. This means that even if you just built the Leonardo's Workshop and possess Gunpowder, your archers will upgrade to only pikemen if you also have Democracy. Same thing for the warriors only upgrading to legions and not to tanks as I hoped.

4. Lot of times it is useful to build it, not for yourself, but just to deny the AI of the upgrade possibility.

Thats not what I found. If you have the tech to do the full chain of units (eg Archer to Pikeman to Rifleman to...) they fully upgrade to the latest. I've had my opening warriors upgrade to tanks with the workshop and catapults to Artillery, and this is on deity.

On deity I had mine go straight from Archer to Modern Infantry one game.

Really? Then either my game is buggy or there is something wrong with my attention to detail or I am doing something wrong. Most likely, it is the combination of the last two possibilities, so I will go ahead and check again. Thanks for this information, and I hope what you are saying is true because I would rather admit to my subpar gameplay than to have a buggy game! :)

Still need more input, thanks

Earlier today I had completed gunpowder research, and had started pumping out riflemen.

A couple of turns later, I completed Leonardo's Workshop, and none of my archers were upgraded to riflemen. This may have been because I had not researched Democracy (for pikemen). My warriors, however, had been upgraded to knights.

For the ultimate in fun, try to locate the lost city of Atlantis, without actually triggering it. Then right before the LW is complete, discover Atlantis.

Cruiser, I'm not sure what more input you need. Finish LW and whatever units have upgrade paths open get upgraded. Hodory is definitely wrong in that they only jump 1 upgrade, especially because all my ships end up as cruisers/battleships.

I just can't believe how incredibly powerful this one wonder is. The moment I complete it I immediately go on the offensive with my new army of uber units.

You need the full chain of upgrades for it to work, otherwise units will remain unupgraded.

However come to think of it, there was one time where I had a sole catapult when I had cannons everywhere else, I had long ago finished metallurgy so it was a bit odd, maybe there is an issue here.

If you get a unit after you have built LW they won't upgrade. i.e. Upgrade everything to modern infantry/tanks/artillery/cruisers with LW. Find a barbarian village that gives you a catapult. It will not become an artillery. Not sure if that is what happened to you but just a thought.

Or if you have one in a build queue that finishes after LW is built.

I mean why/when it does not upgrade all unit.

Thank you. you mean if get democracy to use LW to upgrade archer to rifleman is 100% work ?

Same for me. All my archers upgraded to Riflemen last night, which was a great bonus to my city defenses.

This is one of my favorite wonders that I try to get every game.

You must have the necessary techs for upgrade. Anything found after its discovery is still same old same old.

When I was playing, a normally built leonardo's workshop worked perfectly, but a gold-rushed one did nothing, maybe coincidence, maybe something more

LW rocked for me last night. I was playing as Japanese and on a whim decided I wanted to make some knight units since I was being attacked by 2 other countries. So I started pumping out Knight armies and even after making peace with the other countries I kept one city putting out knights. Next thing I know I have about 10 knight armies so I build Leo's Workshop and POOF I have 10 tank armies. I build a few artillery units and rape the other countries. LW is VERY nice if your technology is up where it should be.

From my experiance, if you rush a tech or discover it the same turn as you build LW you wont get the upgrade for that unit, but if you get the tech for the new unit at least 1 turn before you do get the upgrade. I discovered combustion and used a great builder to rush LW and it didn't give me tanks. I had saved recently so I went back and I discovered it on my own and built the wonder later and it gave them to me.

My problem was that I discovered Metallurgy right before LW was completed - but it was still within the same turn. As a result, my catapults did NOT turn into cannons as I had hoped.

I went back to my previous saved game to make sure I finished metallurgy one full turn before I allowed LW to be finished (I put it on Trade Fair which takes longer, so that I could immediately turn it to LW when I wanted). As soon as LW was done, I went to EVERY city and fixed what was being built to make sure it was the upgraded one and not an old one from long ago that was taking a long time to build.

I did wish that if I had a rifleman (from KT or capturing city), that everything would upgrade to that unit whether or not I had it. But that perk would easily be turned into something people would corrupt.

I think you also need to have the tech to obsolete a unit. So, for instance, you need democracy to obsolete archers AND gunpowder to enable riflemen in order to get from archers to riflemen. Having democracy without Gunpowder gets your archers upgraded to pikemen.

yeah LW is glitchy to say the least

you have to have every tech up the line for it to upgrade properly. if you skip democracy (why would you but that's another debate) then you cannot upgrade to rifles or modern infantry

its a wierd system but I'm sure there is a code reason why it is that way

I had all my archers turn into riflemen yesterday after LW but I think it is because I had all the techs without rushing. In a game later yesterday I rushed to LW since another civ was making a go of it and they didn't upgrade. I know it's sketchy but I think you have to have all the lower techs in line with the units complete for it to work. VERY nice when you have 40+ archer armies suddenly convert to riflemen!

This brings another question though, if another civ has already built it will yours still upgrade if you do, and can you even build a wonder if another civ already has it?

Leonardo's is simple.

If you have the tech for a unit, and your unit is of the same lineage as the tech, finishing the building will upgrade the unit.

So:

Archers>Pikes>Rifles>Modern

Horse>Knights>Tanks ? I know I'm missing one here.

Catapults>Cannons>Artillery ? Same as above

Etc.

An example of something that is possible is to use Oxford for a random future tech and figuring out which future unit is easy to tech to. While teching, spam that unit from all cities and, in your highest production city, build the Workshop. By the time the Workshop is done, the new tech for whatever unit you want will be ready and you'll have a ton of that unit.

Note: You do NOT need subsequent techs when using Oxford nor do you need everything in the lineage of the unit in order to tech up to it. In other words, if you have archers, you do not need pikemen and rifles teched in order to get modern infantry.

The teching in Civ makes the Workshop a game winner.

The reason could have been because you didn't have a line from your old unit to your new unit. You need a clear tech line from your old unit to your new unit, however, you don't need each upgrade for it. It all depends on how you tech up. I know for a fact you don't need rifles in order to get modern from archers.

The Tech Tree makes it weird and can make it seem like you need every tech in a units lineage in order for it to upgrade but you don't.

Also, no, if another civ has built a wonder no one else can build it. This means that if they finish the wonder while you are building it you have wasted a ton of hammers.

Leonardo's is simple.

Not true if you have the tech required to obsolete a unit AND the tech for a unit in that lineage it will upgrade

Def
Archer>Pike>Rifle>Modern Infantry [Democracy required for Archers to upgrade to any, Gunpowder required for Pikes, etc.]

Off
Warrior>Legion>Knight>Tank
Horseman>Knight>Tank

Siege
Catapult>Cannon>Artillery

Sea
Galley>Galleon>Cruiser

I think it qualifies as a bug since it is counter intuitive.

I noticed last night that when I built LW my archers all upgraded to riflemen. I had all the tech required for the riflemen and even a few built. My knights however did not upgrade to tanks because I did not have combustion completed. From this I think it will upgrade everything to the highest completed level of that tech tree. I could be repeating what has already been said, just stating an observation.
