Through the Pipes Quest bug

I've been playing through the quest "Through the Pipes" lvl 110 and have gotten all the way to the final part of the quest where you are supposed to confront the racoon with Fichu. The only issue is that the NPC's are not spawning so that I can interact with them to complete the quest.

I've tried using a scroll to leave the area and reset the final room
I've tried Killing myself to leave the area and reset the final room
I've tried going to the lobby/character select screen to reset the final room


I've tried everything I could think of multiple times.

You are stuck in the final room and cannot leave since the quest will not allow you to back track at this part.
