So I did little tests and what I found out is that indeed George is causing some issues. After repairing and rearming under WPN >UTIL page the weapons had empty circles. When I engaged manually ARM mode they go solid again but after that I was unable to use George as my CPG he just won't and fire. Usually I let George arm the weapons otherwise he wouldn't shoot.
Another interesting thing I noticed is that if rotor brake is set to lock it wouldn't let you repair even when engines and battery are off unless I switch the brake back to off. I don't know if it was made intended or not..just sharing.
