Hi, I'm using InteractiveBoard (this doesn't use ProtocolLib) to create custom boards. My server is on 1.8.8 with paper and with version 4.8.0 it doesn't give me problems. I needed to update Protocolib to 5.0 because my anticheat works only with that version. After the update I noticed the boards (image) were bugged. I asked InteractiveBoard'author for support to the and he said that the problem could be caused by "protocol lib packet listeners delay entity spawn packet so entity metadata packet gets sent first".
