Disconnected after trying to enter trial of sekhemas 3rd floor

Completed the second floor. While trying to enter the third floor, I get disconnected, saying the terrain generation is out of sync with the server.

Exact message: The terrain generator for the client is out of sync with the server. Please create a new instance and try again.

I tried going back multiple times, and I always got the exact same message and disconnection. I did manage to enter the trial of sekhhemas 3rd floor multiple times before. This is the first time I have had this issue.

I can't find my other reply in the forum (to delete it), but as it is exactly the same bug, I put it here too.
I have the same problem trying to go to the 2nd floor.
I have used the item given ascendency point too.
