I thought this issue was fixed in 1.4.4 but it seems to have returned. It only happens sometimes when entering a Multiverse-Portals portal to depart to another world, using Multiverse-Core. It seems to only be packet id 128 at the moment, and other times just a complete disconnect. If the player tries to rejoin they'll immediately get kicked again, and again, and again. In the console it says the player disconnected with reason disconnect.overflow. I understand that a bad packet is when the client receives a packet that contains incorrect data, so what is packet 128 and when does it normally get sent? I appreciate any help, thank you. Bump.
