One of the mods I have (Mysterious Bear's Epic Necromancy) has added a script that causes my game to crash to a few npcs from the same mod. I can't find any console command to let me clear the scripts from the npcs. I've tried using the "dispelallspells" console command and had no luck. I've also test a fresh save file to make sure this script was the issue and determined that it is. For anyone more familiar with the mod the script I'm referring to is the one to replace npcs with fresh zombies when they're killed, this script seems to stay on the battlemages that hunt you down even if you no longer have any ancient zombies, and whenever one such of these npcs dies there's a high likelihood of a crash to desktop.
