I'm having a strange issue with the NPC Gerevick on Dantooine: He doesn't have a model. When I first encounter "Him" in Khoonda, he has a conversation with a holorecorder, but he has no model. I can mouse over the space he should be standing, and his name pops up, but I can't interact with him, because there's nothing to click on. I found this a weird curiosity, nothing more, since that's a short interaction at best.

(Potential Spoiler Alert)

It's becoming a crash bug now that I'm in the Enclave Sublevel, and have to fight him. He still doesn't have a character model, and the game is crashing whenever I engage in the fight. Sometimes it's immediate, sometimes I get a few actions in, but it always crashes and I have to Ctrl+Alt+Delete to get my computer back. Has anyone else had this issue? I didn't see any mention in my browsing of the discussions. If so, is there a known workaround? I'd really like to not lose all of the progress I've made to this point.
