Why cant mayors abandon production runs?

[shogunnamedmarcu]

I would like the ability to abort a production run of an item before its completion if I want to. I work in manufacturing and there is almost NEVER a time during the manufacturing process where you couldn't just take what you have and toss it in the trash while losing only what resources you have already put into it. but you gain the TIME that it would have taken to complete the production. Time can be very valuable in this world. And needs often change in this game where new challenges are thrown at you constantly.

Interesting, guess I've never really run into that specific of an issue.

I generally stop production of something by denying the resources (set trade depots, ores, mines, etc. so they won't deliver resources locally) or turning off the manufacturing component (edit a factory, click the production component's button to turn it off). You won't be able to stop whatever they're manufacturing at the time, but they won't be able to manufacture any more until you re-enable it.
