So, yesterday I was browsing the latest mods, and downloaded "The Haunting of Breezehome" and "Fuz Ro D-oh". Then I went into the Midden, tried to transform into a Vampire Lord, and while I did transform the armor didn't load up and my weapon as dragging on the ground. After maybe 2 minutes the transformation completed. When I attempted to revert back, it simply would NOT. So I loaded a slightly earlier save. Went into the college courtyard, and transformed. It took a bit longer than usual, but everything worked fine for the most part. So I reloaded into the save in The Midden. Transformation was still broken. So I exited out, and uninstalled both mods. The problem still persisted. and then when I tried to load an earlier save file, the game crashed. So, I uninstalled all my mods pertaining to Vampire Lords, but the problem still persists. Does anyone have any idea what happened? EDIT: As an addendum, I installed the Unofficial Skyrim Patch, and did some more testing. I can transform perfectly fine, but in the Midden the transformation still bugs out. It actually works now, but it still takes forever to trigger. However once I leave the Midden, if I attempt to transform again, my character freezes in the transformation animation. I seem to have fixed the problem. I installed all the Unofficial Patches (Dawnguard, Hearthfire, Dragonborn), and the problem seems to be resolved. I guess I'll leave this here in case anyone encounters a similar problem in the future.
