Well We have played several games with "living world" enabled and haven't had any game killing OOS issues. The only close call was after about 400 turns I went to war with Amelanchier and took his holy city of the Leaves (named Bruti) and the next turn it would go OOS. We tried more than 4 reloads, but nothing worked. Everytime i took the city there would be a problem. So I took other cities and avoided Bruti for some time, no problems thereafter, even after I took Bruti some turns later. Very strange, like Kael has mentioned before, OOS issues could be caused by a series of certain events happening at the same time, and that is very hard to track down. But the taking of cities seems to be an issue for many OOS problems of late. If anyone else has noticed this please let us know.
