Despawn Tweaks — Modern Port for Minecraft 26.3 (Fabric)

Fixes cases where mobs that picked up items stay around forever.

Vanilla despawn logic can leave mobs that picked up equipment permanently preventing correct despawning. Despawn Tweaks tracks those mobs and keeps their despawn handling correct — their no-action timer is reset instead of despawning while carrying items, so loot-carrying mobs behave as intended.

Now with a modern port for Minecraft 26.3 (Fabric) — mechanism only, no GUI.

What it does

• Mobs that pick up an item are tagged and protected from despawning while carrying it
• Mobs marked despawntweaks.shouldNotDespawn are likewise protected

Port changes vs. the original

• The original's structure/spawner tracking system and its Forge config API dependency are not ported
• The core despawn protection is preserved

Modern port notes (26.3)

• Java 25 · Fabric Loader 0.20.1+ · Fabric API 0.165.0+26.3
• Built and verified in CI via GitHub Actions, including a headless runtime test that launches the client, joins a world, and quits cleanly

Installation

1. Install Fabric Loader for Minecraft 26.3
2. Install Fabric API
3. Drop despawntweaks263-*.jar into your mods folder
