Now, however, there is no transition behind the door - you open it up and there's just nothing there. No transition, no quarter, no nothing; presumably, it's been this way since the Myon update.
Description of Bug Experienced:
There is no transition into the quarter in the NE corner of the 2nd floor of Myon's Great Tree, when you open the door there's just nothing there; it should be (always has been, at least) the only unique, mansion-sized quarter in the Tree - it costs significantly more to buy (and significantly more in taxes) than the other 7 quarters in the tree.
Steps to reproduce the Bug:
Open quarter door. Experience nothingness.
Expected Result:
A transition into one of Myon's mansion quarters.
Actual Result:
The call of the void.

Additional Information/Notes
I assume that the wonkiness with this quarter transition is linked to the overhaul of Myon - several of the other quarters that shared the interior this one used to have had their transitions deactivated before Myon became arboreal and were moved into the Elven Quarter/Elven Hall, and the previous owner of this quarter just never got around to reporting their quarter being nonexistent in the two RL months of time following this change.
