So far, I've noticed a lot of bugs and glitches, such as when I'm using the shout Soul Tear I get a message saying my vampire blood boils in the sun even though I am not a vampire, I have the werewolf perk. There were also times where Durnehviir was following me like a follower when I didn't even summon him and he once was just circling Fort Dawnguard. I think Bethesda should of tested the DLC several time's before releasing it and possibly then fixing the bugs. Overall I think it's a good DLC but still wish they'd patch the bugs.

Forget it, they don't care bugs.
