I saw lots of posts concerning their farmers only searching for coconuts or watering the field. So I expected my farmers do that too, but they tend to go coconuts first, fish second, crop third. Coconut source is always low, so first choice makes no difference whatsoever. But I prefer my field picked it clean ASAP, so their tendency to go for the crop last makes me micromanage a lot each time the field regenerates. I wonder what makes them choose which part of the source to go first? Is it affected by current food stockpile size, maybe?
