I have a space platform that makes a lot of Space Platform Foundation, to build itself.
However, that platform is done now, and keeps making Space Platform Foundation.
I wanted to put this to use, and requested it in my Cargo Landing Pad, to build other platforms with.

While other things the platform makes are automatically shipped down, it never sends a shipment of Space Platform Foundation, even though I've requested them. Removing all other requests from the Cargo Landing Pad still doesn't result in a shipment of Space Platform Foundation.

I can manually drop it just fine, but it never ships on its own.

What gives?

...aaaand I figured it out.

As long as the platform has ever requested Space Platform Foundation from the planet, it remains with a 0 in the construction requests, apparently. And while an item remains there, it will never be auto-dropped to the ground, even if the requests is 0.

Toggling "Auto request missing construction materials" of and back on cleared the list and made the shipments start happening.
