Unexpected packet received during server login process

I'm using the latest snapshot, I'm getting these errors randomly on the console:

Looks like something on your server is sending invalid messages to bungeecord which is triggering that, try replicating without plugins on either waterfall and a 1.13 server

Closing, this isn't an issue caused by waterfall (nor can we do anything about this beyond ignoring bad stuff), something on the server is sending invalid information to the proxy.
