Has anyone had any luck changing up the setting and/or turning off certain parts of the mod to stop the CTDs? I love this mod. However, it is getting really frustrating with the crashes. I've lowered my map size to standard and I am playing with 16 civs. I'm sure that that is contributing to the crashes (size/# of civs). I don't want to lower either anymore. I usually play on even large maps with more civs. Lag isn't really an issue. In my current game i'm about to get rifleman on Snail speed and it takes about 3 seconds between turns but I crash about every 10 turns. I really don't want to quit that game because a very large world war is about to start but the crashes and the redoing turns where I move 50+ units a turn is getting frustrating. Would turning of revolutions help, you think? Has anyone had luck mixing up the components to get a more stable playing experience? Edit: I'm playing the latest beta build. Here are my game settings: Using a custom ROM_Full_of_Resources_300 map. Which is badly bugged when trying to lower tundra/ice and such. Marsh and arctic don't show up but tundra takes up 80% of map. If I turn them right off (arctic/tundra) then I get all grass everywhere. worked out though with a smaller map and lots of civs. I also tried an updated version of FoR and had the same results. Standard sized map Continents Conquest only Ancient start Snail speed No city flipping from culture No Tech Brokering Limited Religions Start as Minor Civ Multi Production Multi Research Surround and destroy Adv Diplomacy Barb Generals Assimilation Great Commanders Culturally linked start Realistic culture spread Larger cities Religion decay Expanded Castles Arctic and city parks Meteorology Early bldgs Civic bldgs Historical wonders Guilds Modern corps Adv Nukes Trying out some of these new options as i've just come back to Civ4.
