My mage Teclis was in wrong fighting dark siders and mainly using the explosion spell. When I would kill one with an explosion spell, it kept crashing me. It did this twice in a row so i stopped hunting there. I was fighting them in the entry tunnel when they died. If you need more info to recreate this let me know what you need and I'll try to provide it. Thanks :)
Unfortunately, this crashing is probably something unique to you and your program. We often find whacky things or areas that will crash some people but not others. Maybe you just need to not follow the dark side... Luke.
