Not sure of what happened here.

My player said that they simply were moving items from their inventory.

Server keeps crashing whenever the same player gets in.

Actually caused by Extra Sounds which is a client side only mod. I declared it as such as well but apparently it still gets loaded. Ditch Extra Sounds from the server and you should be fine. 😉

Oh wow I didnt notice that. Thanks, will do.
