Demon form + jellyfish character effect crashes game

Demon form + jellyfish character effect crashes game instantly. Unfortunately the character in many cases will remain in demonform for some time. (this locked me out of my character for hours) I recently did it again to test it, thinking maps would put me back in town and remove demonform but no I'm stuck crashing on my witch until the server resets my character's "demonform" status.
