Hmm let me look into it! Is the worker just moving food in and out of the building storage, or is it filling up with non soybean food items? Or something else entirely?

Sorry for the late reply, but apparently steam didn't notify me that someone had started a discussion.

Usually just fills it up with Soybeans, but if storage space is low/far it fills up with other food stuff as well
Thanks for the reply, no matter the time
