Pathing problems
 

Everfrost: An orc trooper keeps pathing in to the newbie canyons.

Halas: female rogue GM Ysanna MacGibbon is living on the roof of her guild instead of the first floor.

Dungeons: Creatures often don't path back to their spawns properly. Once back at their spot they disappear from sight but will still attack passers by if KoS (and they reappear). As this happens in cramped tunnels I suspect this is linked to the Halas bug and the mobs are pathing back and hanging just above or below where they should be, forcing their model out of the visible part of the dungeon.

Finally found this guy. Should be fixed, pending update.
