i know it sounds odd but did you restart tne game and tried if it's working then? are your employees set to take care of the grow? maybe you did standard before and forgot to assign them to toasted or amazonian?

Sometimes I find that picking up an object and removing it or placing it somewhere else fixes the issue. You can even pause, pick it up, place it down, pick it up again and put it back, and everything goes back to normal. Can be weird sometimes, I've seen it with the factory and the stores, all components.
