I've been lurking CF for a couple months now and have learned a great deal but I still have some unanswered questions that are bothering me.

Resources. Each resource gives you a special bonus like +smile or +health (more if have certain buildings), but when you hover over the Resource it also gives another bonus (supposedly) like +1food or +1hammer. Does that mean it gives +1 food on the *tile* that you improved or that you get +1 food for ever city that has that resource connected? I've yet to figure it out even going into WB to help me solve it. Also, resources do *not* stack in any way correct?

Also, a found an interesting bug, or so I think it's a bug. I played a Warlords 2.08 game as the Ottomans last night and got involved in a 4000 year long war with Mansa, I believe. The city was situated on a strip of land 1 tile wide and was the only connecting piece to the rest of my empire and was thus the point of all attacks. I had the Ottomans UU, the archers fortified in the city. After a couple thousand years each of my 6 units had over 100XP each. When I finially researched Rifling so that I could upgrade them to Riflemen and storm across the map with their upgraded/promoted goodieness; I ran into a problem. Upon upgrading the units their XP fell to 10/xx and so I couldn't upgrade them at all. Intrigued by this I upgraded the units and then went into WB and manually gave them their XP back to what it was before the upgrade. Also, I tried giving them their promotions first and then upgrading them. This then dropped them back to 10/xx again but at least this time they got their promotions in. Is this a bug or a feature? If it is I'm pretty sure I have a save of this game that I could send somewhere.

Thanks for you help on this.

Resources don't stack in any way, correct. Any hammer / food / commerce bonuses only count for the tile of the resource (and only if it's being worked by a city)

When upgrading a unit, its exoerience is capped at 10. This simulates the fact that veteran swordsmen will have to relearn some of their ways when changing their weaponry to maces, for example.

Ok, it just didn't make any sense that when you were in the F4 screen and started trading resources why it would list the +1hammer modifier if I couldn't take advantage of it. I guess I will be more caring when I accept those resource trades from now on.

Thanks for the info the 10 XP cap as that was quite shocking when I saw that he went from 130XP to 10...

i often try to not upgrade a unit until it reaches its next promotion, because of the demotion to 10 points thing. one trick i learned recently from these boards is to use the lowbie melee units (warriors, axemen, swordsmen) and promote them as City Raiders (up to 3 if you can). later you can upgrade them to gunpowder/rifle units ... those higher units can't get CR promotions, but they do keep their old promotions when upgraded. a CR3 rifleman with other promotions is a beauty to behold.

Yeah, that hammer in that screen is misleading, they should really get rid of that with a patch.

Yeah, it's a bit confusing, I didn't get it either. As I've gathered it, only the +1 health and happiness bonuses stack in every connected city, the +1 hammers, food or commerce do not (they just give +1 on that particular tile).

As for XP, maybe it's a little harsh to always drop back to 10, no matter how much you have when you upgrade. Perhaps it would be better that the unit would lose, say, 2 promotion levels. So if you had 50, you would go back to 26. If you had 65, you would go back to 37. And so on.
