This is an issue that I can't seem to find anyone else talking about. So I started "Blood on Ice" a few… hundred… hours ago. However, I didn't sell the strange amulet to Calixto. So I got tired of having it in my inventory and decided to complete it to get rid of it. I completed it in a few minutes (I have done every mission in Skyrim twice, once on 360 and once on PC). However, this time as soon as I completed it, my game keeps repeatedly crashing.
I thought it was mod related, but after disabling them all it still happens. I reloaded an old save and had no problems before completing the quest. But, even with my mods disabled, as soon as I complete the quest I can't save, fast travel, or leave Windhelm without crashing to dashboard. I am running the Unofficial Skyrim Patch and have disabled all mods that have anything to do with modifying graphics, interiors, exteriors, or character models. I thought it might have something to do with the amulets code because of it changing to the Necromancers amulet so I ditched it on the second victim before finishing the quest. Didn't solve it. I tried uninstalling and reinstalling the game, and power cycling. I am out of options. I am playing on Xbox One because it has the ability to run it better than my PC. If I had the option I would run it through scrubbers but I can't. Does anyone know what I should do? I don't want to just not complete it because that is giving up. Also, like I said, permanent quest item stuck in inventory. However, I am 177 hours in and can't just restart. I am really hurting here for an answer.
