We have came to understand that the ATI video cards are having a problem reading the Vertical_Symbols.dds. We are working on a fix for this, but it seems that most of the code is in the BTS exe. and therefore has not been exposed to modders to change. For those with a ATI card try this quick fix as the extra yields are for a upcoming mod and not needed in 1.20 . So for people with ATI cards navigate to BTS/Mods/Woc 1.20/Assets/Art/Interface/Symbols and delete that folder for a possible fix. For ATI cards only. Another interesting but untested idea was pointed out by Elucidus, located here, http://forums.civfanatics.com/showthread.php?t=208058&highlight=vertical_symbols. As all of us have Nvdia cards this issue never cropped up, we are now aware of it and are racking our brains out for a fix for it. I'd like to know who has a ATI card so we can work with you to fix/resolve this issue. For now try deleting the symbols folder i mentioned above.
