Join server, everything teleports roughly every two seconds, get about ten seconds chat delay, after about a minute I disconnect with either no error or "An existing connection was forcibly closed by the remote host", server console says "lost connection due to TranslatableComponent key='Disconnect.Timeout'".
Skype starts to break up as if the server is somehow eating all my bandwidth and others on the server start to lag - both fix as soon as I DC.

Both my internet connection and the hosts is absolutely fine on all other servers and games.

I manually forced a debug crash before disconnecting and have attached the report.

Hope someone can shed light on this.
Thanks.
