Troubleshoot Items Stuck Between Hoppers and Modded Blocks

Why Items Get Stuck

Without Cooldown Coordinator, vanilla hoppers and modded blocks often have mismatched transfer rates or timing, causing items to jam at connection points. This mod prevents that by synchronizing when blocks can accept items.

Diagnosing the Problem

1. Verify Cooldown Coordinator is installed and loaded

2. Check that the modded block you're using actually implements the mod's interface

3. Ensure vanilla hoppers haven't been overridden by another mod in a way that breaks compatibility

4. Look for error messages in your game log mentioning the mod

Fixing Stuck Items

If items remain stuck:

  • Try replacing the modded block with an alternative from a different mod
  • Add a buffer hopper between problem blocks to absorb timing mismatches
  • Consult the modded block's documentation to confirm it supports Cooldown Coordinator
  • Consider using only vanilla hoppers if the modded block lacks proper support
