--- Comment #30 from rumleech@yahoo.co.uk 2012-09-09 04:24:43 CDT --- OK, I've been running some test games to find out which DLC's are affected by this bug. My results are; Harald, Hawaii, Babylon and Korea suffer from mid-game crashes. Genghis, Spain & Inca and Ancient Wonders seem to be OK.
It looks like the crash occurs when the DLC Civ enters the Renaissance Era but I'll need to do further testing to be sure.
Ancient Wonders has it's own bug (the wonders don't show up at all) and Hawaii messes up the start up menu but these are stories for another day and another place.
