@@ -14,6 +14,7 @@ These changes will (most likely) be included in the next version.
 - It is no longer necessary to have recurrent waves for an arena to work. MobArena automatically creates a "catch all" recurrent wave in case the arena session reaches a wave number that isn't covered by any other wave definitions.
 - Entities outside of the arena can no longer target players, pets, or monsters inside of the arena.
 - Tab completion for `/ma kick` and `/ma restore` now uses actual player names instead of display names.
+- If the world of an exit warp, leaderboard, or linked class chest is not available on (re)load, MobArena now throws a config error instead of failing silently later down the road.
 - MobArena's internal version checker has been rewritten. It now uses the resource API of Spigot instead of DBO. It's also a lot more lightweight and caches results for up to one hour.
