not exactly. I was playing a game for a while and it crashed(non-maf). so I loaded the autosave and all culture was gone from the entire map for every civ. so I loaded a couple older autosaves and the same thing.
also, I loaded an old carthage game (everything looked fine, culture-wise)and after applying the svn updates in game, then saving, then loading the save, now it too has the same problem of no culture anywhere in the world.
this savefile loads improperly, or at least the culture is all messed up lol. this is in svn 3832
