to reproduce: have 2 drawers and place chute between them.
once the drawer that is above the chute is empty. replace it with another filled one. chute will not extract from said drawer anymore.

This issue has been marked as stale because it has been inactive for 3 weeks. It will be closed if it remains inactive for another 3 weeks.

This issue has been closed since it has been inactive for 3 weeks since it was marked as stale.

Use the Drawer Key and lock the items they are receiving into it. At least then if empty it won't lose record of where to place them. I've got a massive storage room that takes items all day from a monstrosity of auto farms.

I believe this is true with funnels too though even if the drawers locked...
