--- Comment #42 from rumleech@yahoo.co.uk 2012-10-07 09:12:55 CDT --- I think I've found a workaround for this bug. If you enter the DLC menu and untick Gods and Kings, accept the change then go back into the DLC menu and retick Gods and Kings the it seems to work fine. Not only do you get through the Renaissance without problems but the Ancient Wonders show up as the should and the Polynesians don't mess up the choose civilization menu on setting up a game. Loading a game requires you to go into the DLC menu and untick Gods and Kings. It's all a bit fiddly but it all seems to work. I'm sure there are technical reasons for all this but I'm not nearly talented enough with Wine to figure out what they may be.
I'm going to investigate it further and if anyone else wants to join in I'm sure it will help.
