I have a new glitch which I haven't seen reported. I finished Dawnguard 2 days ago, & am just meandering. Serana is my follower. I have never been a vampire, in DLC or main game. Not even in Soul Cairn. Was a werewolf only for Companions quest line & cured myself weeks ago.

Twice now, while traversing outdoors, the screen gets hazy, I see a phrase in the top left screen containing the word "vampire". I check the Effects menu & suddenly I have "Champion of the Night" & "night footfall?", & weakness to sunlight. I check my Effects all the time, @ least 10 times a day, & this just started. Also, in the log I am recorded as having bitten 1 neck, so apparently I'm a lousy vampire.

I do not save; I reload my earlier save & all those attributes are gone.

This is not a problem glitch, merely interesting, but has anybody else experienced this?
