please provide details.....

also, you cant expect protocollib to support modified servers. if you modify your server software, so are expected to fix issues yourself.
if there are things protocollib could do to make your life easier (and that also doesnt make shit worse for others), you could always PR those changes.

edit: just found the project (https://github.com/Linux-4/CloudSpigot). the author is violating the copyright of mojang, msft and every contributor of bukkit, spigot and paper (including myself)

I understand, I already stopped using this server jar, thanks and sorry for the waste of time.
