Recently on my server I asked the command /scoreboard teams add Founder. I then downloaded the world from my server and used the NBTExplorer software to put the founder's prefix in red before my nickname. After doing this manipulation I put the world back on the server but now my friends and I are trying to connect and we get the message "The length of the receive string is longer than the maximum allowed 19> 16"
