I stumbled upon this while completing a quest, I assume it's to the final boss or scaly Pete. Just wondering what it is.

Me and my friend were having an ok run and then this happens. Like why the hell did it continue to go even though we were on door 50?

I was doing my daily quest and joined a pub, then I see this. Very odd just wondering if anyone else has experienced this?
