Fixed
- Villager duplication (look-at-npc task): fallback on villager so it was saved to the world and survived restarts/crashes, piling up duplicates. Now non-persistent yand remove on every arena when it ends..
- Arenas Fixes: locations failed to resolve when the world wasn't loaded yet, marking arenas as unconfigured (can't enable, empty preview), and the shutdown save, then wiped the spawns from disk. Locations are now stored raw (world name + coords) and resolved lazily, so data survives an unloaded world and saves never erases it.
- NEW tasks more than 4+ tasks.
