I just experienced a pretty annoying bug.
I had the aircraft setup, APU running, FMC programmed and GSX ready for pushback, I turned to dave to remove ground power and chocks.
I first tried to remove the chocks without thinking about removing groundpower first, what this resulted to was that now suddently nothing worked of the groundservices. I could no longer remove the groundpower, neither the chocks. I tried diffrent ways to get away from this:
1. Disable GSX - No effect
2. Use panel states - No effect
3. Use the other dave - No effect
Is there any solution to next time this may accure, never happend to before.
