Hey fuller, about the problems I had with the AC130: I found out that it isn't compatible with Peral's A-10C Mod. When I activate the last the following error shows up when I enter the AC130:
No entry 'bin\config.bin/CfgVehicles/USAF_AC130U/Turrets/MainTurret.missileBeg'.
Perhaps this info is a little help to fix the bug. When the A-10 is deactivated everything works fine.
