🚀 What's New in SimpleDuels 1.0.2

🔒 Anti-theft system — The headline feature

Duel items can no longer be stolen, traded or smuggled out.

• Permanent stamping: Every kit item is now stamped with an invisible, permanent tag identifying both the duel and the player it was given to. That tag survives renaming, enchanting and anvils — it cannot be removed.
• Instant destruction: A stamped item is destroyed the instant it stops belonging where it is: picked up by the wrong player, dropped, stored in a chest/ender chest/shulker, dragged, crafted with, moved by a hopper, or carried out of the duel. A 2-second sweep also destroys anything that slips through.
• No more double armour: Teammates in a party duel cannot loot each other, closing the "double armour" loophole.

👥 Party duels (2v2, 3v3, 4v4)

/duel server opens a queue anyone can join through a clickable button or /duel server join <name> (partial names work, e.g. join pepi for pepito).

• Atomic joining: Teams split automatically when the queue fills. No more 2v3s — joining is atomic, two players clicking on the same tick can't overfill a lobby.
• Queue management: Expires after 2 minutes; disconnected players free their slot automatically. The creator is locked into their own party (prevents announcement spam), while joiners can leave freely.
• Cooldowns & Mutes: 10-minute cooldown between parties (with admin bypass). Use /duel server ignore to mute announcements.
• Smart autocomplete: Autocomplete lists only players who actually have a party open.

🛡️ Team rules

Teammates are completely immune to each other — melee, arrows, TNT, end crystals, beds and respawn anchors. Knockback, armour damage and shield breaking are all prevented together. Enemies hit you normally, and your own explosions still hurt you. (Applies only inside party duels; 1v1 is untouched).

💀 Party duel lifecycle

• Fight to the last man: Dying no longer ends the duel — you spectate until your team resolves. The duel ends when one side is wiped out (double elimination is a draw).
• Forfeits & DCs: Forfeit, disconnecting or leaving the map all count as a loss and the duel continues without you.
• Victory messages: Lists only the winning team with their remaining hearts. Dead players show up as Muerto — someone who quit is indistinguishable from someone who was killed.
• Spectator updates: /duel spectate now displays party duels with both rosters, live hearts, and dead players marked.

🎒 Inventory safety — The critical fix

Players were losing items in party modes. Root cause: the restore wiped the inventory before verifying a backup existed.

• Double backups: Now everything is backed up twice (database + memory). The inventory is never wiped without a backup.
• Verification: The item count is verified after restoring, and it's re-applied automatically a second later if something else emptied it.
• Single-execution: The restore is now strictly single-execution, and players who already left a duel are never touched again when it ends.

🎨 Display & configuration

• Heart glyphs moved to config.yml (lang is for messages only) and are fully editable.
• Heart counting verified by running the algorithm: 3 health correctly shows 1 full + 1 half.
• config.yml and lang.yml now auto-merge — new options appear on update, your customised lines are never overwritten or deleted.

🐛 Bug fixes

• Team spawn placement: No more stacking on each other.
• Arena leak: Parties where everyone left now correctly release their arena.
• Stranded spectator self-heals: Fixes only players the plugin itself put into spectator (OPs in spectator on purpose are never touched).
• Intruder ejection: Anyone entering an arena uninvited is returned to the afterwin spawn immediately.
• Full command blocking: Blocked during duels, including chat ClickEvent commands.

✨ Optional

• Team-only glow via ProtocolLib (soft dependency — the plugin runs identically without it).
