I have a server on latest version of forge and my client is also on that version of forge but if I'm an operator i get kicked and stats "[07Sep2019 17:41:00.151] [Netty Epoll Server IO #3/ERROR] [net.minecraft.command.arguments.ArgumentTypes/]: Could not serialize net.minecraftforge.server.command.EnumArgument@4f20cf64 (class net.minecraftforge.server.command.EnumArgument) - will not be sent to client!" but if i'm not operator i can join just fine. but if i get oped while in game it just kicks me.
