I installed BUG 3.6 and then I installed BAT 1.1. I installed BUG 3.6 for multi-player (meaning Program Files\...\Mods). BAT 1.1 installed standard (meaning My Documents...\Mods).
I started a game using the BAT mod and chose 12 civs total with me being American civ. Once the game started I hovered over my initial Warrior and noticed that it stated that the upgrade for this unit was the Incan UU Quechua. I exited the game.
I started another game but this time loading only BUG 3.6 mod. Same setup 12 civs, I am American. I hovered over my initial Warrior and it again said the upgrade for this unit was the Incan UU Quechua. I exited the game.
I started the game again with no Mods, same setup 12 civs, me being American civ. I hovered over my initial Warrior and no upgrade for this unit was listed.
I believe this is a bug and that the upgrade for this unit as an American civ should not be the Incan UU Quechua.
Please let me know about this.
I'm getting exactly the same thing after installing bug 4.2. In my case, playing as Korean but indicating the Quechua upgrade as next for my warrior. I followed the thread after mcorey's report but didn't see any resolution
