when you place a sign on a server (not tried on single player) it will kick u and not let you back on
EDIT: when i go to sign into any servers i get "Internal Exception:io.netty.handler.codec.decoderexception:java.lang.IndexOutOfBoundsException:readerIndex(9)+length(1) exceeds writerIndex(9): UnpooledHeapByteBuf(ridx: 9, widx: 9, cap:9)
How is this resolved?
I only see the duplicate link, but that's not really the same issue.
