I've been using patterns to make paths through out my village, just to spice up things and stop grass deterioration. With so many patterns, flowers, and bushes littering the once mostly open field, it's gotten me wondering the title question.
Similar in vein to trees, if I placed enough paths and flowers, over the entire map, except about 10 or so spaces. Would those 10 spaces contain the 3-4 daily fossils, daily pitfall seed, and random daily gyroids? Or would they just "spawn" under something else and not show up for the day?
