Join Status Update "Invalid Join Status"

[Sho Minazuki]

I am unable to change the join status of an RP I am running. This is the RP in question.

I specifically get the message "Invalid join-status" in the bar at the top of the page, and it is unable to change.

Known bug. Unfortunately nothing can be done until Mahz returns from his foreign job.
