Exception with the latest ProtocolLib version #608

[AerWyn81]

Hi,

Having issue with the latest ProtocolLib and papermc latest versions. ProtocolLib : #608 Papermc : #347

As long as holograms are enabled on my plugin, I can't connect, I crash with the exception below. If I disable them, I can connect.

Packet encoding of packet ID 78 threw (skippable? false)
java.lang.ClassCastException: class net.minecraft.network.syncher.DataWatcher$Item cannot be cast to class net.minecraft.network.syncher.DataWatcher$b (net.minecraft.network.syncher.DataWatcher$Item and net.minecraft.network.syncher.DataWatcher$b are in unnamed module of loader java.net.URLClassLoader @36aa7bc2)

Do you still maintain the lib? @unldenis

[unldenis]

Try the latest release and let me know if it still gives you the same error.
