woodelf - how do you get information on the cause of a CTD?
By 'bad' graphics, do you mean a problem with the actual .dds files themselves? The only new graphics I've introduced have been the leaderheads - everything else is from the original game, apart from the technology placeholder art which is from the barebones mod. Wouldn't a faulty graphics reference in an xml file cause a crash every time, rather than only sometimes?
