This happens very rarely so I don't think there is much we can do about it. And I think even if you find out easy way to reproduce it, we'd have to call it an engine bug (actually we can do it right away )
Oh man, that's too funny to even get mad about. "Check out my amazing 3D bomber micro guys" I would have liked to see a t1 UEF MAA hit that thing while it's doing stunts.
