Mission editor crashing and seemingly corrupting mission while saving

[Nadel]

Since 2.8 the mission editor will frequently hang. It seems to happen the most when saving a mission, but once the mission file gets in a "bad state" this seems to happen frequently even when trying to make any change to the file. After crashing and relaunching DCS then opening the mission the mission, the map will stay all blue for an unusually long time as if it is failing to load the map at all. Attempting to save, make changes, or fly once this happens has a high chance of crashing. I've had moderate success with restoring previous versions of the mission, but it seems to reproduce again after some more mission editing.
