I've noticed a few things recently. First off, my game freezes for a moment everytime I enter my home. Second, I can't seem to use smithing potions to get my armor rating ridiculously high anymore. I've even tried different armor sets. Third, is there a point in feeding anymore? I go for days without it, and nothing happens to my character's apperance, and no one attacks me anymore. I chose to become a vampire lord after siding with the Dawnguard, and everytime I change into that form, the powers and visual effects take several moments to appear and become available. It also tends to take a while to revert back to my normal state. I'll change, and be stuck as a black figure with wings. I've tried uninstalling and reinstalling Skyrim on my Xbox Hard drive, but it didn't help. I'm afraid to try to delete Dawnguard, because I don't know what it'll do to my saves. Does anyone have any idea what I should do?
