Describe the bug
When using an 1.8 Server with latest ViaVersion and latest ProtocolLib, connected through a BungeeCord proxy, on a 1.9 - 1.12 client, the connection terminates when listeners to packets of type MAP_CHUNK have been registered on ProtocolLib.

Expected behavior
We don't want the connection to terminate
