Steel produced, counter says 0, can't build

If there is steel, but the counter says 0, this means you probably have some buildings in queue with steel aready. That may be everything from machines to pipes or wires. What does it display, when you hover over the steel-entry in the ressource list? Does it say xxx of xxx? If so, and the first number is bigger, this means all of your steel is already planed to be used elsewhere. Maybe your dupes cant reach that spot, and so the steel is still there, but its planed to be used. 

Please check this out.

Hi, if you don't mind could you please upload the save file so we can take a look?
Also as SharraShimada mentions, sometimes the steel is allocated for tasks already, worth checking!

Thanks SharraShimada and klei. Ruby for your suggestions!

The problem kind of resolved itself somehow. I tried manually moving dupes over steel that was lying around and they could move to it. However, while part of my qued up buildings was completed over the course of a long time, some weren't. 

I had some steel lying around in one spot from decommissioned rockets, bunker tiles and gantries. And there was a ladder leading to the spot in question. Nothing was broken. But I replaced the ladder segments with new ones and whaddya know. My resource tab all of a sudden lights up with a couple tones of steel Im sure I had all along!. 

Would it still be relevant for me to upload the save after it's been resolved, I kinda played on for another 300 cycles by now after my little issue was resolved. If so, how exactly do I do it? Same way as with pictures? (I'm kinda new to klei forums btw) 

Thanks for your input guys!

Not necessary for the save, glad it's resolved.
