Resources missing in global inventory although they exist

Maybe I should have added that right away, but here's the save file of that colony

The Spacefaring Laboratory.sav

Did you queued up all your ceramic or is that place reachable?
If one of this is true it just means that you have no spare ceramic left after everything queued to build is built, also I see a "building lacks resources" so this could be it if instead, that place is unreachable it simply means that the game does not count unreachable resources as available. 
I would load your save file to answer those questions myself, but my PC is not strong enough.

Thanks for your suggestions. But no, there are no build errands anywhere on the map. Also the bin is definitely reachable since I filled it up by setting it's priority high to get my dupes to deliver all the ceramics to this spot.

Hmm... so I dragged a general cancel command across the whole map and the ceramics reappeared. So it really was bound up in some build errand. But I'm really sure I didn't see any errand on the map. So maybe there were some invisible build errands after the last update...
