auto-advance oversight: when one does not have the storage for the required amount of food it will stay in the current section even if it does not provide all of the required materials.
EG: section 10 (10000-11000) requires 500 food, but section 9 does not provide stone (and as water is not yet harvestable, stone is not mineable by the old man) which is needed for expanding food storage to that point.
