Bug Fixes

  • Fixed a critical bug where players would get stuck in the queue indefinitely and never be released
  • Fixed the server-side keep-alive timeout causing players to be silently disconnected while waiting in the queue (extended from 15s to 2 minutes)
  • Fixed the queue not progressing on Arclight hybrid servers due to NeoForge chunk futures hanging indefinitely in the Bukkit bridge
  • Fixed a race condition where the queue position display could become out of sync after a player disconnects
  • Fixed players bypassing the queue entirely when the server was at vanilla player capacity (they now queue correctly)
  • Fixed the config file crashing the server on load if it contained an incompatible format from a previous version
