[b18] Enemies inactive after reentering dungeon

[Grey]

I quickly popped out of Dreadfell to sell some stuff before level 20 (trying to avoid the Crypt encounter for as long as possible) and when I came back all of the enemies were stuck in place and wouldn't perform a single action until I attacked them.

Any other things to note about this ? they seem to move fine when I come back, even after a save/reload :/

Haven't tried reproducing it. Anything to do with going into another Zone and using shops? Also it was still the same creatures on the level - they hadn't respawned.
