Hello I am running a server using SpongeForge 1.8.9, as well as the latest 1.8.9 beta version. A problem has arose with regards to a player joining.
If a user joins without the proper mod, they get this message in console
[22:35:14] [Server thread/INFO]: player0 lost connection: Mod rejections [FMLMod:pixelmon{4.3.0-beta4}]
However, as soon as they join everyone gets fatal error until I restart the server:
[22:35:19] [Server thread/INFO]: player1 lost connection: A fatal error has occured, this connection is terminated
[22:35:19] [Server thread/INFO]:
[22:35:22] [Server thread/INFO]: player2 lost connection: A fatal error has occured, this connection is terminated
[22:35:22] [Server thread/INFO]:
[22:35:25] [Server thread/INFO]: player3 lost connection: A fatal error has occured, this connection is terminated
[22:35:25] [Server thread/INFO]:
[22:35:27] [Server thread/INFO]: player4 lost connection: A fatal error has occured, this connection is terminated
I am 100% certain that this is the cause, and it has happened almost 4 times already. This is game breaking cause it will literally crash the entire server.
