I have already completed the A night to remember quest quite awhile ago, but I had to go back to Morvunskar for a quest to get a staff for someone at the Winterhold College. Well I walk into Morvunskar and hear people fighting so I am like wtf and run further into the area. Turns out an invincible Sanguine is walking around the place punching all the enemies NPCs in the area lol. Anyone else have this happen?

Good ol' uncle Sanguine.

Yep, it's pretty funny.
