First off, just gonna clarify, it's an error, not a crash. Second, if you don't know what I mean by joining one server from another, I mean with a plugin. (For example, as mineplex does.) The error is only one line, so I'm not gonna put it in a spoiler. And, here it is: [07:22:57 INFO]: Client> [07:22:57] [Client thread/INFO]: [CHAT] Exception Connecting:IllegalReferenceCountException : refCnt: 0 @ io.netty.buffer.AbstractByteBuf:1173

 

 

Thanks in advance, TDashDog1.

This is caused by mineplex's proxy server {the one that lets you connect seamlessly to other servers}

Go speak with them about it, It was fixed though.. They may of changed something and reintroduced it recently.
