Didn't see this mentioned, but wanted to say the following.
Twice I've been with a mage when doing a turn in with this lil guy. Both times he was in a big rock and wouldn't come out. The first person could get close enough to hail him and get the text but not close enough to hand him items. We had a GM nuke him out of the rock and atone him (or something similar) so he could do the turn in. This was a year ago and at that time, the GM didn't know why he was in the rock.
However, the 2nd time was about a month ago. Same thing. The guy was in the rock, but one of the other group members said sometimes you can walk into the rock from the backside, and sure enough we were able to walk INSIDE the actual rock itself and do the turn in.
