PotD Floors 56 and 60 Crashing

Hello,

Currently I am trying to progress through PotD, however upon entering floor 56 the game freezes and requires a reboot of the game. Once I reboot all proceeds fine until completion of floor 60. Once I try to exit floor 60 I am met with an infinite loading screen. If I try to exit and reload the problem persists until I am automatically removed from the PotD. This results in no EXP gain and/or credit for completion.

This has happened 4 times now.

Please help. :(
