I've similar problem to this - twice - in Act 1 rat that I need to kill to get bone for Edmond at very beginning is stuck in wall. Figured it wasn't such a big deal and carried on. Am now at end of Act one and the last guy in the Battlefield quests has retreated into his tent and I can't speak to him to let him know I've got his black pearl & get my experience points. Assuming it's similar to him being stuck in wall. Can't click on either of them though can sometimes see them, sometimes not - though they're visible on mini map.
Checked the post and saw comments about alt-tabbing - I've been doing that a lot so that probably caused it but certainly doesn't fix it. Note you mentioned hex file you sent to fix Ankhumar problem and wondered if you had something similar for me? Would like to fix both problems but most bothered by battlefield bloke.
Thanks in advance!
Muriel
