I have been playing Minecraft on my server for a few days, and the past month I encountered a bug with the overworld, every time I try to aces to a certain chunk disconnects the player showing this message: "Internal exceptionio.netty.handler.codec.decoderexceptionjava.lang.nullpointerexception".
This is my log: https://mclo.gs/UbON1D8
As you can see in line 1798, that happens when a player connects to the server, I download the world to my single-player, and doesn't seem there's an error and I can load the terrain without a problem, the only way to escape this error is using /tp to get out the player of that zone while connecting, I don't know a possible solution or what is causing it, I'm still able to play in other dimensions or staying away of the problematic chunks
Thank you very much!
