Unable to access trial 4 shekhema.

Hello,
I just finished the boss on floor 3. Unfortunately, I'm playing with a controller. The merchant was next to the exit portal, I pressed "A" thinking I would access the merchant, but it made me exit the trial.
I try to rejoin the trial, thinking I won't have access to the merchant anymore... I simply can't access floor 4 trial anymore:
"The client's terrain generator is no longer synchronized with the server, please create a new instance."
Do I have to start ALL over again?
Could you move the merchant portals away...
Could you fix this bug.
I would like to not have to start over.
