When entering a particular part of my world, my client violently disconnects from the server with the following exception:

Internal Exception: io.netty.handler.codec.DecoderException: java.lang.IndexOutOfBoundsException:readerIndex(11)+length(1) exceeds writerIndex(11): UnpooledHeapByteBuf(ridx: 11, widx: 11, cap: 11)

Not sure as to the cause, could only assume it's some type of block that is suddenly loaded.
