When a hostile mob targets one of these villagers, event.getEntity() is the hostile mob and the owned NPC is returned by event.getTarget(), so this condition remains false and the targeting proceeds. This defeats the documented targeting protection and can leave zombies or other mobs permanently attacking the invulnerable NPC; check whether the target is owned as well.

/av command gate
A non-op granted only VotingPlugin.Commands.AdminVote.NPC cannot use these commands: VotingPluginMain.registerCommands() assigns the existing root permission VotingPlugin.Commands.AdminVote to both /av and /adminvote, so Bukkit rejects the command before the new handler's leaf-or-admin check runs. The same applies to a sender granted only the advertised VotingPlugin.Admin override; either wire the permissions through the root gate or document and declare the additional required permission.

When an NPC is within 0.5 blocks of a chunk boundary, loadedArea requires both the anchor chunk and the adjacent chunk containing its bounds to be loaded, but this handler only records and reacts to unloading the definition's anchor chunk. If that adjacent chunk unloads while the anchor remains loaded, the NPC stays active even though its original spawn/ownership invariant is no longer satisfied, particularly affecting Paper/Folia boundary positions. Match unloads against the same surrounding chunks checked during creation and retire every affected NPC.

When entity cleanup is transiently rejected during a chunk unload or configuration disable, cleanupFailed retains a closed RuntimeNPC and resets cleanupQueued; on the next chunk load or reload, this branch merely sets reconstructRequested and never calls retire again. The slot therefore remains permanently in cleanup pending and the configured NPC cannot return until a full plugin restart, so retry cleanup for a closed predecessor before deferring reconstruction.

When all 64 runtime slots are occupied, removing one NPC and immediately creating another with a different ID can leave the new definition dormant: the retired NPC still reserves its slot while cleanup is pending, so this check skips the new NPC, and forget only schedules reconstruction for the retired NPC's own ID. Once cleanup releases the slot, nothing retries the new definition unless a later mutation, reload, or relevant chunk event happens, even though its area is already loaded; trigger a general reconcile when cleanup frees capacity.

There was a problem hiding this comment.
On ordinary Spigot/Paper, getFoliaLib() is null—the existing BukkitCompletionScheduler, VoteShopPurchaseService, and SharedMysqlPointMutator explicitly handle that legacy case—but every successful registry load or mutation reaches this unconditional dereference through reconcile(). The resulting exception is caught and merely reported, so definitions created in already-loaded chunks never spawn, and storage-worker-triggered removal cannot clean up live NPCs. Route these operations through the normal Bukkit scheduler when the Folia adapter is absent.

The current packaged dependency constructs FoliaLib unconditionally in BukkitScheduler’s constructor, including the Spigot/Paper path. The exact PR JAR was checked. Defensive null checks in sibling callers do not establish that this adapter is normally absent. Which supported server/runtime path leaves getFoliaLib() null after successful construction? I have preserved the current implementation pending a reproducible path.

Coverage includes real command matching, Bukkit permission inheritance, durable storage failure/recovery, directory aliases, cancelled/unrelated interactions, multiple players, replacement, transformations, occupied-chunk unloads, transient cleanup rejection/recovery, full-capacity replacement with a different ID, an unloaded current reservation releasing capacity for a different loaded target, bounded unloaded/failed creation, delayed creation and owner scheduling.

Latest-head hosted clearance remains pending.Native Spigot/Paper/Folia deployment and visual client checks have not been performed.
