Werewolf quest bug is the most amazing, it says that you are cured after you do it and all guards still say that your character have a "wolf smile" or something like this, and if I am not wrong the day count as werewolf keeps going on and you can't also turn into vampire. I'd say to no one who wishes to become a vampire to get to be one werewolf, also Arch Mage's robe + Morokei mask make the character head disappear ( edit: it just happens some times, I don't know exactly why of it).
I also wish you guys could please make a fix for werewolf cure quest, because it is just kind of sad to get a character bugged after hours playing >.> I had to create another character to become a vampire, which is also horrible, the character face begin to get ugly than a frost troll's face, why all vampire npc got their face "normal"? excluding that they look very pale, really, it's horrible to know that only the player character get ugly with the vampirism ..... not drinking blood have made my character get ugly face, drinking blood still have got him to get marks on his face, so I had to load a save before turning into vampire as I didn't expected such thing to happen. I really would love to player character don't get physically affected by vampirism, but just get pale as the other vampires do get, not even the Master Vampire npc have a weird face, he is just pale as the many other vampire npc. Er well, that's all >.> So far loving the rest of the gameplay.

Also, how do I get to a vampire character "lv up" his vampirism? It's by not drinking or by drinking blood? I looked into Skyrim Wikia but they didn't told exactly how it happen

Edit:
What in the name of oblivion .... I just post saying that even Master Vampire doesn't have ugly face and I just found one with a very ugly face.
