this happens when I log into version 1.8, and then log into the 1.20.1 server

error 1: https://prnt.sc/SaWnZY-p6c7M

então ativei a opção Dwaterfall.packet-decode-logging=true

error 2: https://prnt.sc/_y7zw9d15RIU

BungeePackFix_1.1.5-beta-1 waterfall-1.20-562

removing bungeepackfix solves the problem and they are not kicked
