Good morning,
1.) Yes, we have some code interference - this will be fixed with next update.
2.) I see this as well and we will try to fix it. Two ways to avoid it: A.) Don´t click "resume last flight", instead choose "new flight" (should be same parameters). B.) IF you get the APU not running, flip the switch to START, wait until APU started and then connect both APU generator switches.
Cheers, Jan
