(Use AntiDupePro-X.X.X-mc26.jar for Minecraft 26.x)

[3.3.2] - 2026-06-11
A false-alarm crackdown. If your console ever filled up with repeated
[DUPE] alerts, or honest players got flagged, this update is for you.

Fixed

• Alert flood stopped. When another plugin blocked an item pickup
  (vault, claim and loot-protection plugins do this), AntiDupePro could
  spam hundreds of CRITICAL dupe alerts per second for a single item.
  It now waits one tick and only reacts to pickups that really happened —
  and a given item can only trigger that alert once.
• Worn gear counted twice. Equipped armor and offhand items were
  double-counted, so a worn elytra read as 2 and caused bogus
  "has more than the ledger says" alerts.
• Double chests were invisible. Items moved in and out of double
  chests weren't recorded at all, which slowly built up false alarms.
• Chest moves measured, not guessed. Shift-clicks into nearly-full
  chests, number-key swaps, offhand swaps, double-click gathering and
  drag-moves are now recorded by what actually moved. This removes a
  whole family of false alarms (and a loophole dupers could abuse).
• Mining drops counted correctly. Fortune could make the real drop
  differ from the prediction; the plugin now looks at the real drops.
• Placing blocks / dropping items is also double-checked one tick
  later, so other plugins undoing those actions can't skew balances.
• More stable on busy servers. Inventory checks now run on the
  correct thread (proper Folia support) and database writes can no
  longer collide with each other.
• Suspicion cools down properly. It now only fades while a player
  has been quiet, instead of fading constantly.
• Stash teleport links now work for stashes in the Nether and End.

Added

• Villager trades are tracked. Buying a tracked item (e.g. an
  enchanted book from a librarian) is now recorded properly.
• Enchanting a book is tracked — the new enchanted book is credited.
• Alert severity now follows your own alert_thresholds settings
  instead of a built-in list of "important" items.

Good to know

• If players were wrongly flagged before this update, run
  /adp ledger clear <player> once to reset them.
• Plugins that hand out items directly (shops, kits, vault plugins like
  ElytraVaults) are invisible to any event-based tracker. AntiDupePro is
  built to not punish players for that — but if a specific item still
  alerts too eagerly, raise its number in alert_thresholds
  (materials.yml), or ask the plugin's author to call the
  recordSystemGrant API.
