cyclotron blew up and now the server crashes on startup

[BayCan59]

i tried using the cyclotron, and overheated. and the last thing i saw was the chat message that i died of a nuclear explosion before the server crashed. now i can start the server fine, but whenever someone joins the server immediately crashes.

here are the crash logs in order from the initial crash, the first time i tried joining, and the most recent time i tried joining
