What happens when you have an armory, and you have insufficient radiation to power it, but plenty of metal?

My impression is that production on the armory essentially freezes.

So then I am wondering what happens with the metal that would have been spent on the armory?

Does it just sit there, as resources associated with a failed "tick forward" for the armory, or is the metal re-allocated elsewhere, if possible (ex. a Factory).

I encountered a weird scenario, where my radiation was very low, and my metal was maxed out.

The metal accumulation rate was reporting at -17, but the bar wasn't dropping, which would suggest to me that some of the metal wasn't being used at all.

I therefore built a couple of extra factories to suck up the metal -- maybe not the right thing to do.

So I get this impression that in the scenario above, my production effort was at -17, but my actual usage might have been +10 or something.

I'm curious if it might be possible to separate these numbers in the UI, so that I can see attempted use vs. actual use.

Seems like it might be friendlier, so that I am not wondering if I am blocked, and can plainly see when there is a problem.

Don't know. Just a thought.

Maybe it would even be possible to highlight the facilities that are operating below capacity, so that I can find them quickly and turn them off, or something?

Maybe bind to a tab or hotkey, so I can cycle through them easily?

Also am curious what happens to the excess, and whether it is re-allocated, as described above.
