So I made the mistake of picking up a cooking pot with my hands when I had no backpack
Turns out, whenever I try to do anything that removes the cooking pot from my hands, the server freezes. Everything stops "responding" and I get an infinite "receiving..." notification.
This happens whenever I try to put a weapon in my hands via the hotbar, when I press the X in the inventory on the cooking pot, when I try to drink from wells, drink/eat something directly from the ground, etc. Everything is responsive up until the very exact point I try to remove the pot from my hands.
I'm pretty sure this affects the entire server, because whenever I leave, I cannot rejoin the server for a small period of time and people seem to leave it in large numbers
