Extraction businesses start producing on their own
When a mine, well, farm, logging camp or other business that needs no inputs finishes construction, its first recipe is now scheduled automatically as a recurring task, so it starts producing right away.
Businesses whose recipes need no inputs used to open with an empty production queue: the building was finished and staffed, yet produced nothing until you scheduled a run yourself.
Now, as soon as such a business completes, its first recipe is added to the queue as a recurring task. If the first recipe cannot run there — a crop this city's climate cannot grow, or a product you have not discovered yet — the next one that can is chosen instead.
You can still cancel the task, change the recipe or add more runs from the business's production queue. Businesses opened through the guided first-business plan keep the recipe you chose in the plan.
