I've been dealing with it since update to 1.8.0 with the mod team I'm working with.
Yes. I just did it all files successfully validated. I aslo deleted native and sandbox then run steam verify integrity reacquired the folders and still crashes. I am currently working with a modding team we haven't changed any map atmosphere xml or the like. This crash happens anywhere on the map even in battle's. you might also mention that not everyone is experiencing the crashes (which makes it more likely to be a native issue)
