Boss - Unbelievable Custom Monsters v6.2.0

Advanced custom monsters & AI plugin with skills system and a clean UI. Folia supported.
  • Improve | Better multiworld plugin compatibility if a Boss region is on a different world. We now load regions after the server has fully booted.
  • Fix | Solved "Collection is empty or null" when no Bosses are installed and attempting to spawn one.
  • Fix | No longer print a console error if update check fails due to BuiltByBit endpoint being down.
  • Improve | Better handle invalid PlaceholderAPI extensions.
  • Improve | Avoid crashing on old Paper builds when the following bug occurs.
  • Fix | Solved a few false reports being sent to sentry.
  • Fix | Solved some cases where an empty error message was sent to chat as an empty line.
  • Misc | Silenced "Cannot invoke "org.bukkit.inventory.ItemStack.getType()" because "<local2>" is null" due to it being a citizens bug, we're awaiting a fix on their end.
  • Improve | Stability and performance updates from the underlying library update.
  • Improve | Improved stability in legacy entity metadata (<1.14) for Bosses in unloaded chunks.
  • Fix | Solved "Cannot invoke "org.bukkit.inventory.ItemStack.getType()" because "item" is null".
  • Fix | Solved "Cannot invoke "RegionManager.getApplicableRegions()" because "manager" is null".
  • Fix | Solved world names in Boss spawning limit being quoted in single quotes, breaking them. Note that your world names should be alphanumeric without spaces with only underscores, if you use non-standard world names then the plugin might not work as expected.
  • Fix | Solved sounds not playing.
  • Fix | Solved language keys still being used when set to empty or "none".
  • Fix | Solved issue "cannot find class Goal" when Citizens plugin is installed but malfunctioned earlier.
  • Fix | Solved issue "The name of the profile contains invalid characters" when a Boss dies with a custom player skull.
  • Fix | Solved "Boss X not loaded" when attempting to delete already removed Bosses.
