Finished substitutions erroneously shown as in progress

[Atemu]

This happened during a remote store + remote build (--store ssh-ng://machine where the store machine has remote builders configured).

nom says it's substituting some paths whose dependents have already finished building which obviously can't be correct.

Speculation:

This might be due to the fact that the path was already present on the remote (but not the local machine nom runs on) and therefore isn't considered?

thx for the report. I witness something like that regularly myself. Not sure yet what exactly is going on there.

[Atemu]

As a workaround, you could at least consider a build/substitute to be done when a dependent starts realising.

I hope we can find a better solution.
