Dexion remains hostile after feeding

[Schattenu]

Hit an annoying issue, I'm doing the Dawnguard quest Prophet on the vampire side. After releasing Dexion from the magical barrier and beating him into submission, Serana and I both sheath our weapons automatically and I used Vampire's Seduction on him, as usual. He stands up and waits, and I feed on him as the quests tells me to do, but he turns hostile again and he and Serana both start trying to kill each other. I've reloaded saves both inside and outside the cave, but it keeps happening. I use Better Vampires, would that cause any problems like this? I've searched around but couldn't find anything. :/

 

Edit: Nevermind, magically fixed itself. *shrug*
