I don't know if it's been suggested before but to me it isn't logical that you can botanize and find acorns, but the source of acorns (oaks) do not have a harvesting option. You could make the harvesting of acorns seasonal like olives and grapes and such so as to not nerf botanizing acorns (people with high botanizing would still get good QL acorns at the same rate). I want to see some oak farms going here.
