I play DAWNGUARD on PC. I didn't install any Mod except DAWNGUARD.

When i become a Vampire Lord and quickly revert back to human, I became a odd naked Vampire Lord.

I can cast spell and open inventory but when i open skill menu it shows Vampire Lord skill tree. I can pick items and talk to NPC.

BUT i cannot turn back to normal human or normal Vampire Lord, I press Q or Z nothing happens i cannot open the Q menu anymore. Is
there anyone know how to solve this problem???

I dont know why I cant post Link to show the picture.
