Been getting this crash and error multiple times while playing new Tac-Ops DLC scenario. The crash occurs fairly regularly (5 times within an hour) but it happens seemingly randomly doing game-play or when reverting to a previous save. I'm not running any mods other than some community produced Steam Workshop scenarios which shouldn't effect playing a BI produced scenario.
Edit Update: Although I have had the crash during during game-play, it seems to happen mostly when reverting to a previous save.
