This might be true for all production. I haven't tested.
But since my colony is now rather large, I need to cook stoves to be able to create enough food. But the second (or third) can't be used. Noone uses them, and when selecting a colonist and rightclicking on them, they can't be prioritized.
Is this a known problem?
It works fine for me. My current colony has two stoves and both get heavy use. Did you add bills to both stoves? Each stove has separate bills, so if you set them for one, the second one won't have any unless you add them there as well.
It might be there is no path, is there anything in front of the stove? I know its obvious but insure there is power.
my people are not using even one... i am playing in god mode... and have been experimenting with save file editing (can make things buggy/not load). but none of my people seem to be using anything for crafting??
