I have been playing Skyrim Dawnguard on my Xbox 360 and found it very irritating because of vampires attacking the cities now and them without giving any break. I know that this game focuses on the war between humans and vampires. But that doesn’t mean that vampires will keep attacking now and then. I think that this must be some bug that must be causing the vampires to attack so frequently. I will be buying this game for my friend as a gift if ever it comes out on PC. I think that developers should fix this vampire attack bug when releasing the Skyrim Dawnguard dlc for PC version.
