im running a server with my friends, we have no other plugins than
BKCommonLib
CoreProtect
EssentialsX
LuckPerms
ProtocolLib
TrainCarts
WorldEdit
WorldGuard
WorldGuard Extra Flags
Every around 20 minutes or so the server crashes and says "Could not connect to a default or fallback server, please try again later: io.netty.channel.AbstractChannel$AnnotatedConnectException"
when we rejoin, everything we placed within like 2 minutes dissapears but inventory data stays the same, for example if i placed 10 cobble, my inventory will not have those cobble anyore but the world does not have them placed. I have tried to repair files but that still does not fix the crashing
