Space Depot

Space Age 2.1 lets platforms parked at the same planet supply each other. But when two platforms share a group, items set to be supplied by Platforms won't be shared between the depot and its clients.

Space Depot fixes that:

• Tick Act as depot on a space platform hub.
• Tick the logistic groups your client platforms request from (source: Platforms).
• The depot gets a <group> (depot) copy of each ticked group, sourced from the planet, so rockets keep it stocked while it keeps providing.
• Each copy is its own section with its own ×, so you size each planet's buffer separately. Overlapping items add up.
• Edit the client group as normal; the depot copy follows.
• The panel warns about depot requests that would stop it providing.

No new items, no new entities. Requires Space Age and Factorio 2.1.

Tips
- Don't wire circuit Set requests into the depot hub: those always request from Platforms too, and stop the depot providing them.
- Clients can use circuit requests; just put those items in a ticked group too, or the depot won't restock them.
