This is making Skyrim near-unplayable, when attempting to transform into the Vampire Lord it simply does nothing, yet I cannot access my inventory or my character menus (the game obviously reading me as having transformed), after a while if I wait patiently, my character will randomly transform into the Lord however will have no spells or powers and revert form also simply does nothing. I heard this was a conflict with Magic Duel, but even after disabling it via its menu and uninstalling it through NMM the issue persists, however it is not the most concerning. Upon summoning Durneviir he clips through the floor, proceeding to then fly through land and mountains as though they do not exist, either that or he simply starts flying upwards in a spiraling fashion (as if he is chasing his tail), this along with considerable Save Game bloating is really starting to annoy me, at first I thought it was my texture mods causing stuttering by eating through my VRAM, but it was not using anywhere near the 4GB VRAM I have on my graphics card, after reading up on it I found that Dawnguard causes some considerable save game bloat and the symptoms were the same ones I was getting.
