I ran in to strange bug at the Priory of the Nine. When I go to the Priory Undercroft and the ghosts appear, one of them tells me that I need to prove my self to them by fighting them. The fight starts normally with the first ghost, but before it loses all of it's healt, it just stops fighting and walks back to the spot where it first appeared. After that absolutely nothing happens. If I attack it, everybody else starts yelling "Assault!" "Guards!" and such and the ghost tries to run away from me. If I keep attacking until it "dies", then the leader ghost sends the next ghost at me. So I guess I can finish the guest, but I am going to get LOADS of assaults on my otherwise so clean record.

Could anyone take a guess what's going on? Here's my BOSSed mod list:

Don't know what's causing that bug, but you could open the console, click on the Knight that's supposed to be attacking you and type StartCombat Player. That should get them to attack you. If all else fails, you could click on each Knight in turn and type Kill Player (which would credit the Player with the "kill") or just type Kill.

Thanks! StartCombat worked like a charm!

Hi, I just had the same problem. Its Ren's Guard Overhaul, just deactivate it till you finish this part of the KOTN. Do this worked for me.
