DupeWatch Advanced Anti-Dupe 1.2.2

Fixed a bug where you couldn't get scanned automatically unless you added a special thing in the config,

added rate limiting so players cant spam items in and out of chests/inventories to stress the server​

DupeWatch v1.2.2 – Faster Performance & Smart Alerts

November 6, 2025

Changelog – v1.2.2

New Features

Multi-Layer Caching System

DupeWatch now remembers recently checked items so it doesn’t do the same work over and over.

Example: If a player checks the same chest repeatedly, DupeWatch already knows what’s inside and skips extra work.

Bloom Filter Technology

A fast check that can quickly ignore items you don’t care about.

Example: The plugin can instantly skip regular blocks like dirt or cobblestone without slowing down the server.

Material Type Filter

Another quick filter that instantly skips items that aren’t being watched.

Example: If you only care about diamonds, it ignores all other blocks right away.

Improvements

80%+ CPU Usage Reduction

The plugin now runs much faster and uses less server power.

Example: Before, checking a chest could slow the server; now it’s almost instant.

Smart Debouncing

Stops multiple checks from triggering at the same time.

Example: If a player quickly opens and closes a chest many times, DupeWatch only checks it once.

Automatic Cache Warmup

The plugin gradually learns what’s being watched after startup.

Example: During the first few minutes after server start, DupeWatch “warms up” and then works at full speed.

Alert System Improvements

Threshold-Based Alerts

Alerts now trigger at multiples of a set number instead of every time.

Example: If your alert threshold is 3, you get alerts at 3, 6, 9 violations instead of constantly at 4, 5, 6, etc.

Clearer Alert Messages

Alerts now show player, item, count, and threshold in a clean format.

Example: [DupeWatch] Player123 flagged Diamond Sword [15/10] means Player123 has 15 violations and the alert threshold is 10.

Configuration Enhancements

Settings are now easier to find and use.

Example: You can change alert thresholds or ignore creative mode directly in the plugin menu instead of editing files.

Bug Fixes

• Alerts now trigger correctly at the right counts.

• Thresholds and intervals now save properly.

• Silent detection messages no longer spam the console.

• Settings now persist when moving between menus.

If you have reported something in the past week its fixed in this update:
Error with adventure classes,
Added a new silent license verification messages option in the main menu,
Fixed an issue with the edit rule gui glitching out after clicking an option,
made edit rule gui more pretty,
and aton more stuff!​
