Even though i have dawnguard, which means my vamp character has undergone certain dawnguard changes (like glowing eyes), when i fast traveled her to whiterun, i was attacked by hostile NPC's. They are acting like they would if i was vanilla stage-4, but i thought that was changed for dawnguard.

Is anyone else having this problem or is it only me?

Maybe the reason why this is happening is that i started dawnguard as a stage-4 vamp, maybe if i started dawnguard on stage-1 and eventually went to stage-4, the NPC's wouldn't attack me. Or perhaps it's just a bug.

Were they the random group of Dawnguard fighters that attack you from time to time or were the guards trying to kill you?

You lucky bastard. I don't have this feature anymore:( Too bad, using my illusion skills was fun.

No it was the guards, as well as non-guards NPC's.

And this didn't just happen to one of my characters, i have another vamp who is at stage 4 and it happened to her as well.

I just reached stage 4, and it said people will attack me on sight. I haven't tested it yet, is it still supposed to say that even with Dawnguard installed.

Please test it, and see if you get attacked.

So what can i do to fix this? Any ideas? Or is it even a bug? Maybe im just doing something wrong and its not a bug at all.
