Lachlan: That problem has come up before: The error you are recieving regarding the Ethiopia and Siam may occure in the diplomacy or victory screens. The problem is caused by a mispelled folder. Look in Conquests/Scenarios/Earth 3.OneBillion/Art/ and change the name of the "leaderhead" folder to "Leaderheads". The mis-spelling causes referencing errors for many Ethipain and Siamese pcx's. Unfortunetly, I can't change the spelling of an existing folder with a patch, so every one who hasn't done so already has to do so themself. But when I finish the lastest update I will re-upload the entire mod for future users (Incremental patches will be avaible for the rest of you guys) @Baron: If they were indeed that far behind in tech, the changes I'm making in the latest update should enable them to research about a third faster. As far as trading goes, you account is favorable: the iroquios nor sioux should have contact with the aztecs Could anyone verify the approximate level of research the Iroquios and Sioux are usual at when you first make contact with them? (provided you're not playing as an american civ) Also, has anybody noticed industrial age music playing during the ancient or medieval eras? Or European civs' city graphics not changing in the industrial age? Also, has anyone besides chosey had a problem with AA units or fighters set to air superiority not working for the player? By the way, sorry I haven't been posting frequently these past two weeks. I will be checking in here and replying more often now. The big update is slightly delayed, but still in progress.
