If a container is destroyed, the items within drop long enough that anyone who is standing on top of or next to the container can pick them up. Then, the items get duped when the container respawns. This is likely the same or similar to Issue #5. How to replicate: - Lead a creeper towards a chest or other container - Stand next to or on top of the container - Let the creeper explode - There's a chance that some of the dropped items get picked up before the datapack can dispose of them.
