Only reason I didn't follow up on that thread is because it's in a Big Picture forum, and I didn't install Big Picture, so it's definetly not their problem, but I didn't want to point them anywhere else either until we nail down which mod is actually causing it. When we do, I'll update over there

Thanks for looking into it
Incidentally, if you didn't notice, there -is- apparently a legit encounter with "Rune Assassin"s in the game during the Tanner murder quest. Just mentioning it since I'm not sure how you plan on "checking your game for Rune Assassin encounters"
