[Valkas]

It is happening every time i am starting mission in quick mission builder: screen shows something what looks like a corner of the map, pointing away from it, sometimes upside down. Switching views, padlock, etc does nothing, and according to map icons all planes are loaded in correct positions. I tried all possible configurations with settings and maps, with no effect. It just happened once after prolonged use of fmb and continue ever since. Yet this bug (?) have no effect on campaign, single or online missions.

It look like this:
Okinawa


Smolensk (no rotation, it appears upside down)


Any advice would be helpful.
