Unable to enter dojo after adding room

[HornedRat]

Me and a friend were reorganizing our dojo and encountered a progress-stopping bug after he added a room (elbow connector attached to a trophy room) and got a lag spike, which prevented me from seeing the room. Afterwards, I tried to add it myself, on the same dead end, and that time we both got to the loading screen, except it got stuck and would never finish loading, forcing us to alt-f4 out of the game. Once we got back in the game and tried to enter the dojo, we got a message saying "Unable to retrieve dojo data. Please try again."

Would like to know if there's a fix I can try for this since this bug completely prevents both of us from accessing the dojo.

Thank you!
