    Hello, title says pretty much whats up. I think it may be mod related, as after I placed a block belonging to a mod (McCrayFish Gun Mod) the server shut down and kicked me out. I've tried erasing player data as advised in some threads here, but problem still stands, every time I start the server, all fine and dandy, but as soon as I join the server shuts me out and closes. The latest log is in the attachment below.


    Its Minecraft 1.18.1 and Forge version is 39.1.0

    Thank you! :)
