Hello! So I just installed 3 plugins which are ItemsAdder, ProtocolLib, and LoneLibs ( i know this is github for protocol lib but i just wanted to explain what i installed onto my server). Basically I got this msg in console right after installing and restarting my server:

[10:53:25 WARN]: [ProtocolLib] [DetailedErrorReporter] Internal exception count: 32!
[10:53:25 INFO]: Error Unable to intercept a read client packet.

[10:53:25 ERROR]: [ProtocolLib] INTERNAL ERROR: Unable to intercept a read client packet.
If this problem hasn't already been reported, please open a ticket
