VillageAI

[2.1.1] - 2026-03-11 - Bug Fix Release

🐛 Bug Fixes

• Village data lost on restart — loadVillagesAsync() and validateVillageData() checked for a "villages" YAML section that was never written; data is saved at root level ("village-0", "village-1", …). Both methods now iterate root keys directly, so all villages survive server restarts.

• Data loss on shutdown (async save race) — onDisable() called saveVillages() which used CompletableFuture.supplyAsync(). On server shutdown, the JVM kills thread pools before async tasks complete, silently discarding the save. onDisable() now calls a new synchronous saveVillagesSync() method that blocks until the file is written.

• VillageValidator NPE on class load — private static final Logger logger = VillageAIPlugin.getInstance().getLogger() was evaluated when the class was first loaded by the JVM — potentially before onEnable() sets the instance — causing a NullPointerException. Replaced with a lazy logger() method that reads the instance at call time.

• /vtrade accept always returned "Quest not found" — The command displayed only the first 8 characters of the quest UUID (e.g. a1b2c3d4), then tried to reconstruct a full UUID by appending "-0000-0000-0000-000000000000". This produced a UUID that never matched any quest. /vtrade quests now shows the full UUID, and /vtrade accept parses it directly without reconstruction.

• VillageManager.restoreVillage() did not populate villagerToVillage map — Members were written directly into the Village set, bypassing addMember(). After a restart, getVillageOf(villager) always returned null for all loaded villagers. restoreVillage() now iterates restored members and inserts them into the map.

⚠️ Minor Fixes

• ECONOMY_UPDATE_INTERVAL = 24000 was 24 000 ms (24 seconds), not 24 hours as the comment stated. Changed to 86_400_000L.

• VillageEconomy.getVillageUUID() returned world UUID — every village in the same world shared the same economy UUID, making trade offers indistinguishable across villages. Now derives a deterministic per-village UUID from the village's coordinate-based ID string.

• updateAllPrices() and generateTradeOffers() looped all ~1000 Material values on every economy update. Both methods now only iterate materials actively tracked in SupplyData, reducing unnecessary CPU work.

• DeliveryQuest.onReward() never gave emeralds — only sent a chat message. Emeralds are now added to the player's inventory (or dropped at their feet if the inventory is full).

• Dead field VillagerNameManager.villageManagers — declared but never read or written. Removed.
