Kicked within a few seconds of joining the server with the following error message:
Connection Lost
Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/72 (ia) was larger than I expected, found 19 bytes extra whilst reading packet 72
Only happening to one player so far. Player is in The End. Other players in the overworld do not seem to be effected.
More testing to follow.
Environment
Clients: Windows 10 and Debian Linux (Both x64).
Server: Windows 2008 x64
Fixed in the next build. See MC-91043
