What is the Bloodgrass Glitch?
The bloodgrass glitch is a very common glitch that happens during the quest to cure vampirism. There is a witch that you must give ingredients to, namely one being bloodgrass, and when you go to give her your ingredients, there may be no option available to give her the bloodgrass. This means PERMANENT vampirism. Unless the PS3 gets the deepscorn hollow add-on from the PS store, there is no way to cure the vampirism.
