A really strange bug. I had vampirism cured after dawnguard was done. then i got werewolf form and im half way through companion quest line. decided to download a mod that lets me be both vampire and werewolf, went to serana and ask for the bite. after wards i transformed as vamp lord, then when i revert i instantly jump back into vamp lord again except i have no spells or attacks or interaction.

Thought it was mod that broke the game, disabled it, went to a save before i acttivated the mod, ask for bite and the same bug repeats.

Any ideas?

oh also, with and without the mod, right after serana bites me i am stuck with this blue glow around my character like im affected by frost spells.
