Fixing Item Transfer Timing Issues in Mixed Networks

Identifying Cooldown Desynchronization

If your item pipes, ducts, or modded hoppers deposit items into vanilla hoppers unevenly, the issue is usually an uncoordinated cooldown. Vanilla hoppers enforce an internal pause between transfers. If an upstream modded block pushes items while the receiving hopper is still on cooldown, items can back up or cause unexpected behavior in item filters.

Synchronizing Block Entity Cooldowns

Cooldown Coordinator resolves these mismatches by notifying connected block entities whenever a cooldown is triggered.

1. Ensure Cooldown Coordinator is present in your game's active mod list alongside your item-transfer mods.

2. Reconnect the modded ducts or containers directly into your vanilla hoppers.

3. Run a test batch of items through the system.

Coordinating the cooldown ensures the upstream modded block entities recognize when the receiving block entity is pausing, waiting for the proper transfer cycle before attempting the next item movement.
