I started DG today, loving it so far. I sided with the vampires obviously, got Harkon to explain everything about being a Vampire Lord, and he told me to speak to Garan Marethi. I reverted back into a High Elf and went to find him, but whenever I try to speak with him he simply tells me I shouldn't be running around the castle as a mortal. All the other vampires give me similar replies, acting as if I'm mortal and threw away my gift and that I should hope that Harkon will be gracious enough to turn me into a vampire again.
So I figured, maybe I need to be in VL form to talk to the guy, but when I transformed everyone attacked me. Harkon still treats me as a vampire though, giving me the option to have him explain everything again and everything.
I'm assuming this is a bug or a glitch because I don't know what went wrong. Does anyone have any idea on how to fix this? I really want to continue the quest.
Thank you in advance.
