I'm not a Vampire, don't want to be one. I haven't asked to be turned into one by Whatshername nor ever let the disease advance - as soon as I've ever been infected I've taken a potion and I check all the time for disease. I'm NOT a Vampire in my Active Effects, there's none of the Vampire Magic nor weakness to the sun etc etc etc.
Yet lately, sometimes when I get into a fight, and it's now two Dragon fights in a row, the screen goes red and I'm informed my "Vampiric Effects recede with feeding" (and I haven't fed on anything) and suddenly I'm a [REMOVED] Vampire in my Active Effects.
Re-load and I'm not a Vampire, then continue on and the screen goes red again and ...
The only way I solved it in The Soul Cairn after about a dozen attempts taking on the big fella while turning into a Vampire over and over again was to turn the difficulty right down to Novice (from Master) and take him out real quick before I turned into a [REMOVED]Vampire.
Now I'm fighting that Dragon on the mountain near Azura, got no Vampire Effects, no Vampires around anywhere, just fighting wolves and a Dragon - and the screen goes red...
... I'm a [REMOVED] Vampire again!
I can hopefully turn it down to Novice again... I hope... and luckily I keep plenty of saves but... it's not annoying nooooooooooooooooooooo!
