Raw Metal Resources at 0

Probably pathfinding problem (closed doors, fallen sand, water reservoirs, e.t.c).  Make sure your dupes can reach this storage compactor. If there is no route for your dupes to resource game interface and building menus don’t take them into account.

Or, in case you have the problem when you load/continu a game:

 

Got this or a similar bug. Pending construction of an Electrolyzer that was not reachable, I derped and removed the mesh tile underneath it. I then set the insulated tile to the left to be deconstructed (already gone in pictures) and then noticed I was told I had no raw metal when I went to replace the mesh tile. Mining new resources didn't fix, and ejecting the raw metal from a compactor did not fix. Save and reload fixed issue. Regrettably, I didn't immediately take screenshots and the uploaded pictures are after the attempts to fix and the reload. Not a pathfinding bug/problem.

Just got this bug at around cycle 65ish. I THINK it may have originated when I put a storage compactor in a cold biome and set it to metal only to cool it off. But that is just a guess. I saved and reloaded many times, even restarted my computer. Tried mining metal, tried deconstructing things made of metal, even deconstructed every storage compactor and still couldn't get metal to register.

I was in the middle of building a copy of the natural gas generator / fertilizer maker setup. Oh well, gonna try a different world. I have the save file attached.

This bug occurs when you place blueprints of items/building/machines that require copper or any kind of metal, each time you place a blueprint the game automaticly puts the resource that it requires in limbo, it disappears from the ore list, when you place too many buildings more than you can afford for ex you place 5 generators but you have metal for only 4 , the metal goes into an ammount smaller than zero, farming and digging won't fix it, the only way is cancelling blueprints , I had this bug and found the solution pretty easily.
