'It's a party!' quest froze
Open, Needs TriagePublic

Description

What is happening:
After dancing with NPC Hullabaloo, the dialoge appeared as normal but the quest log won't update. Went AFK for 10 minutes leaving the dialoge on. Upon returning the dialoge box was closed, my pony in idle animation and the quest didn't update. The marker for the quest (on the map and in overworld) dissapeared as well. All NPCs in the room won't talk.

What should be happening:
The quest log should update for the quest to continue.

Steps to reproduce the issue:
Go throught the quest as normal until you get asked to dance with somepony (I choose NPC Hullabaloo) After dancing talk to him. Leave the dialog box on and wait.
