also, after working on one mission, loading the other gives wrong UI for some items like takeoff (like QGCmissionNavTakeoff.ui) is not shown, but another with less fields is used.

I suspect there is some "resetting" that needs to be done, because any mission loading/editing works 100% when used for he first time after application start.

(And before anyone mention that the attached missions can't be VLOS and think this small piece of the missions are a danger to other traffic, - please observe that I have a CAA approval and NOTAM's active https://www.ippc.no/ippc/aerodromes.jsp?AED=ENSR&FIR=ENOR)

additional info: clicking "delete all waypoints" before loading new file fixes the problem, so the fix may be very easy :)

I'll get this and fix it on monday - going home right now.
