So, I'm not quite sure when this glitch started happening, but whenever I have the amulet of the gargoyle equipped, I am unable to use my summon gargoyle power. When I attempt it, my character vanishes for a short period of time, and no gargoyles appear. Without the amulet, though, I summon my gargoyle just fine. Any ideas on how I could fix that?

I've also encountered a glitch with mist form, albeit a happy one. It seems I can use it whenever I'm not in Vampire Lord form.

Also, off topic, I have no idea where Serana is! I asked her to wait somewhere and forgot to have her follow me, but upon returning there, she was gone. I have no idea where to locate her. Can anyone help with that?
