I've changed it so that everything at the place where the flying ship is moving somewhere else. It also occurs to me that I had some skratti there that moved in wolf form last turn (so they could move through a forest with the forest survival bonus) and then changed shape for storming a castle this turn, so that may be it too.

Let me know if that works. If possible I'd rather not have my guys move away, but it's easier to rule it out if I move everything.
