The update may help with the crashing; however, I can’t be sure what is causing it without error logs. Please enable logging and post the lua error log if you experience a crash. Providing additional details such as what era of the game it occurred, if something specific was happening in game, and what other mods you were using will also help. I’m confident I will be able to track down the cause of the crash eventually. Unfortunately, the new update is not compatible with previous saves.
Great Spy (Brave New World) v. 17
