Game crashes when exiting sometimes

[Worrazen]

DCS Would crash when exiting, I think this has been happening to me since the 1.5 Open Beta, I think it maybe happens if I use the mission editor at any point while ingame, but not sure, but the game works fine inside, never crashed to me while playing.
