Downloaded and updated via the game, no issues. Mission arena, participated, got a leak, accidentally landed on an enemy field, got killed. Waited until the mission had stopped, no issues taking off an entirely different plane.
What I find slightly disturbing is the "forests": There's more trees in a park than in the AH woods. One shouldn't be able to count individual trees from above, and that should be true as well here in the north as in the Pacific looking areas. Of course there's the issue with GV's, but isn't there a way to make them look like forests from above?
