This reminds me of a similar bug I had (might even be the same one) when I accidentally walled off all my dupes in a small cave outside the base. All the material (sandstone, food, etc) in the base suddenly became unavailable - only the stuff inside the cave was shown as "available materials" for construction.

As soon as I deconstructed the wall to let my dupes out, the problem was fixed and everything became available again.

I don't have a save file, but theoretically you should be able to reproduce the bug by simply walling off all dupes in a confined area away from the materials.
