Ah! Yesterday I walked by NPC F.N. the fanatic in the sewers. Clobbered him again, as I usually do. Turned away and started to walk... loading screen. Put me in the basement of the arena in one of the rooms with the Grendols and Clackers.
Additionally I have had reports from a few players of this random teleportation thing happening. I also think that it has happened to me when I was running out past the magic shop the other day. There was a worldshout to this effect the other night, that the bug is know and they are working on it.
Actually, considering the capricousness of gods, I think Laanx is just having a joke on us...
