2.2.0

Please note that stepping on players disguised as Happy Ghasts for a while might result in being kicked by the server for flying. Enabling allow-flight in the server.properties might help resolve the issue.

You might need the latest 2.9.0 PacketEvents development build, which can be found on their description page.

New Feature

  • Implemented Disguise Waypoint feature
    • This will replace the player's waypoint while they are disguising themselves
  • Added support for Ghastling variant for Happy Ghast
