i'm playing dawnguard dlc and it is supposed to let u reach stage 4 vampirism without making NPCs hostile, and it was all working just fine but one day i logged in to skyrim and everyone started attacking me. the weirdest part is that even tho imperial guards in riften also attacks me, the whiterun guards attacks the ppl attacking me and leaves me mind my own business. i was kinda get to get comfortable just roaming around with my stage 4 vampirism and my resist fire enchantments and potions but now i have to drink potions of blood to reset to stage one and make ppl stop attacking me.. is this a glitch or bug of some kind? cuz i haven't done anything weird. is like playing the old skyrim only with dawnguard's quests, NPCs and maps. the only thing i did was complete the thieves guild change of management quest and now every npc turns hostile towards me when i'm at stage 4 vampirism.

am i the only one with this problem?, is there any way to fix this? also, selena doesn't follow me anymore since i told her mother harkon was dead. selena now just bleed on my arrows and that's it

PD: i noticed that after a quest i no longer had the power to turn into a vampire lord but then i loaded a little back and now i can go vampire lord but still NPCs doesn't seems to like me in stage 4 vampirism
PD2: yes i have my dawnguard dlc checked in my data files.

Do you have a bounty?

no, i don't have a bounty.. as i said, town guards attacks ppl who are attacking me and everybody calms the freak down when i drink a blood potion to reset my stages to lvl 1.. i don't understand what the problem is :S

If you are using a Vampire overhaul mod..99% of them brought back stage 4 hate for vampires.

Vampire overhaul mod? don't even know what that is, and nope, i'm didn't installed any mods before this started to happen.. as i said, i just completed the thieves guild main quests till new management and told selena's mother harkun was dead
