i went offline to explore...logged in, changed map to the philipi, then went to tower at A1 i think.
hit F5 view to cruise around the map, throttled up, then hit forward....CTD.
logged back in offline, went to tower, F5, no problems after that...
i figure it was becuase it was just a new map and restarting AH fixed whatever there was wrong. So, no problems now other than the first CTD when i loaded the terrain from clipboard.
