*** In Depth Issue ***

I have a POTD static and we killed the last boss on floor 180. We want to progress to floor 200, however it is not allowing me to join and shows me with a 'locked' icon on the POTD entry picture. I am not sure why since we killed the last boss. No other member has the locked out picture- my fellow raiders are Elthic Nayr, Daelian Cadmus and Kaplan Cadmus.

Please help us so we can clear POTD.
