Well game froze but this time it was different. GUI was "stuck" (it wasnt unresposnsive) what it looks like to be another freeze but the game seems to run, only units dont move around. Even if it seemed frozen i kept it going for a minute or two and pressed the button to speed it up, after a few secs i got the message that i shot down one enemy aircraft even tough everything was static on the map. The enemy plane that was shot down dissapeared from the map, only problem was nothing was moving past the point were it looked like it froze again.
