By the way, I remembered another bug (maybe it was just me), but when the hero's movement points were completely exhausted and he was in a garrison, the computer would tell me: "One or more of your heroes can still move. Do you still want to end your turn?" :)

Then it's worth clicking "move" with him again, and usually it turns out that he has one more move in the other direction (there's a road, the terrain is different), but not in the direction he was going before....
