Go to Quicks/ delete
.last.quick file, just to be sure.
I know 2 instances of AI crashing or when using A (AutoPilot)
Can happen on Carrier Missions or when the Map has strange spawnpoint issues
at the desired Scramble T/O point.
Solutions
On Carrier Missions don't use A to Take Off, use Catapults when avail and/or T/O yourself.
Spawnpoint issue (very rare), simply use another T/O point of the Base in FMB and see what it gets.
A third case of all Planes crash instantly when hit Fly fly Button can occure when you
play incompatible Missions in BAT forcebly, or you are using the Quickselection in QMB,
again, here when using outdated (DBW, HSFX, BlaBla...) quick files to load.
The reasons for this can be various, Map related (layout changes) or other changes that affect
playabillity.
Missions must be on pale to BAT, designed for it or converted to run.
Quicks you must be made in BAT exclusively to work best.
If none of the cases is due, we still have your Logfile to look into and track your troubles.
Best wishes
