When creating a singleplayer world, just before I get plopped into the world, I get kicked out of it with a closed channel exception. The log says "connection timed out", but I have no idea how that could happen on an internal server,that's not even open to LAN. Here's the log: https://paste.gg/p/anonymous/fb39410afac544bd926b3e2a4afb426a It's quite long. Since the error only occurs when trying to create a world, I'd think the error is near the bottom of the log. Thank y'all in advance.
