Trying to find a crash in the server but the console log is spammed with:
[19Nov2019 16:45:05.565] [Server thread/ERROR] [net.minecraftforge.fml.network.simple.IndexedMessageCodec/SIMPLENET]: Received invalid discriminator byte 63 on channel rftoolsbase:rftoolsbase

Literally hundreds, maybe thousand(s) of times.

I know. Busy debugging this right now

Last update should fix this. Let me know if it doesn't and show me the full server log in that case
