Upon attempting to load into my test world, the game near immediately kicks me out with "disconnectScreen.unexpectedPacket". The world worked fine in 1.17.11, but is now broken in 1.17.30, thankfully this is only a creative test world and not anything important, but I feel bad for people who are about to lose their hard work worlds to this grave error.
