I'm using the latest HolographicDisplays build with the UltimateStacker plugin on the latest Spigot-1.14.2-build and the console seems to be spamming: 'onPacketSending(PacketEvent)' - Cannot retrieve entity from ID.

Error: https://pastebin.com/VrtKsine

Thanks in advance!

Maarten.

Update Protocol Lib. If the issue persists, it must be related to #135
