I have also encountered this. Steps to reproduce on 64bit executable. In editor create a soldier, place down zeus gamemaster, start scenario. Place a blufor pawnee (any helo will do it) and, pressing alt change the altitude of the chopper to make it fly. Immediate crash with the access_violation. This does NOT happen with the 32bit executable.

Upvoted. I don;t why anyone would vote against it, for modding purposes.

Looks like the tracker is full of noobs (sigh)

Seriously, some people voting against it that don't have the courage to say WHY they don't like the idea?
