NOTE: The user who encountered the dedicated server crash here

the crash didn't happen the first time upon entering the mirror dimension, it happened when i was using the leap spell from Ars Nouveau to quickly traverse the area, and went to land near a worldgen structure (A chocobo stable from Chocobo Knights of the Crafting Table), not sure if it's relevent, but i'm providing it regardless
but after the initial server crash, every subsequent time i tried to log in, the server crashed again

Better Jukebox is not designed for sidnedness. Removed.
