What the heck! I have seen a lot of strange things playing this game, but this blitz is in a league of its own.
Can anyone tell me how this is possible?
My pretender left province A with no afflictions and a rather large contingent of magic units under his control. Next turn he arrives in province B. There are no battles, and no messages to indicate that he came under attack of any sort. Yet he is now feebleminded. All of the magic units under his command somehow still made the trip with him, but got dropped in the destination province (i.e. they broke formation).
Note: he is immortal, so age isn't an issue. On the plus side he will recover, though probably not before getting steam rolled by the several hundred white centaurs and such in the next province over.
