Server Crash on Client Join

[Hovercat]

Hi, recently I've been noticing that after a client re-joins a time or two (Not using any exploits, I've tested it myself with and without exploits). My server is protected from the most common exploits, I don't know why this has been happening.

the usual way to track those errors is to disable all plugins and test if the error is gone. then reenable every plugin one by one and test after each step.
