There's a limited number of units saved on age transition, plus units to fill commanders. The priority for saving is for units defending cities, so ships are the first to cut. In exploration age you could train naval commanders, this allows saving ships for modern.
I think the red vs. green color indicator only denotes that the city does or doesn't have enough resources for you to trade with. You're very clearly in range of the Greek cities, but the cities might not have enough resources to exchange.
No and no. Be very careful where you put units to sleep, because you may never find them again.
I think your ships are converted to Ships of the Line if you have enough Naval Commanders to contain them.
I think it's not possible to keep them. Maybe if you have only 5 or less Land Units and a Coastal Settlement? But they for sure cannot be packed inside an Army Commander.
Note that they are not limit one per city, but limit one _type_ per city. If you have a bunch of factory resources of the same type (and have enough slots), you can throw a bunch into the same city.
I was able to build it I believe it has to be on grassland?
Does sitting a unit on top of the "conquered IP settlement stop it's unit spawning? Does it take longer or cost more influence to befriend a hostile conquered IP than a non-conquered one or for a friendly one
You need enough money, enough pops and a urbsn tile which has no civilian unit in it. Also you can only buy one unit per turn per settlement.
Weird, I had all those things. The Settler simply didn't appear as an option. It does now, some turns later.
Wow did not know that… thanks very important info to get
Click on the “Show Hidden” button, it should give you an explanation in red text as to why you can’t build/buy something at this time. There are some secret rules dictating what can be bought - for example, if you buy Walls you can’t also buy a unit in that settlement on the same turn.
Maybe you didn't equip it properly?
