Closed darksider1010 closed 1 year ago

darksider1010 commented 2 years ago

Hey, after restarting the server and the player join this server comes following error.

IMPORTANT: The player must be in the near from npc. So that the npc show directly in the tab.

This only happens with a restart My currently Protocollib version is: 4.7.0. https://ci.dmulloy2.net/job/ProtocolLib/533/ The currently server version is: git-PaperSpigot-445 (MC: 1.8.8)

As stated on the site, you should use at least ProtocolLib 4.8.0 (https://ci.dmulloy2.net/job/ProtocolLib/547/), the issue should be fixed then.
