ToME: the Tales of Maj'Eyal

I have occasionally seen Agrimley and the apprentice mage move from their starting locations. This time around Agrimley moved quite far from where he started and I realized why. These neutral guys swap places with the patrols on the world map. This could potentially be game breaking (or at least require a lot of waiting) if they move into a corridor and block passage, like if Agrimley was a little further down in this shot...

That happened to me before. I had to wait until he moves again. But when he moves like this he fights every adventurer group and dies a lot faster.
