please help me, my friends game keeps crashing when the server saves the world.
here is the server log:
[25mar2020 19:10:40.037] [Netty Server IO #20/ERROR] [net.minecraft.command.arguments.ArgumentTypes/]: Could not serialize net.minecraftforge.server.command.ModIdArgument@323ca2df (class net.minecraftforge.server.command.ModIdArgument) - will not be sent to client!
[25mar2020 19:10:40.037] [Netty Server IO #20/ERROR] [net.minecraft.command.arguments.ArgumentTypes/]: Could not serialize net.minecraftforge.server.command.EnumArgument@104b34b0 (class net.minecraftforge.server.command.EnumArgument) - will not be sent to client!
this is the last thing that happens before our game crashes.
