Here I had a solar panel.
I've set an order to build heavy conductive wire, behind the panel base. I precise : panel was still built at this time.
Gold has been delivered by dups, then I've decided to cancel the build. This action buried my gold into the solar panel (same cracking overlay on the panel base).
So I've tried to unbuild the solar panel, thinking about it will get back my gold, but it doesn't work. This gold ended up buried INTO the space.
The panel building order is my last action before the screenshot, not bug relative.
Steps to Reproduce
Build heavy conductive wire behind a solar panel. Wait for the supply, but not for the build itself. Cancel the build order, ressources should be buried into the solar panel. Unconstruct the solar panel, and ressources should be buried into the space.
This issue has not been confirmed by a developer yet.
