I’m just going to message you so the thread stays on topic. I time travel in my games so it takes around 1 month of hardcore running around to achieve dirt paths. If you don’t time travel (or even if you do), the easiest way is to run around the whole town where your paths will be at least twice. Save and quit. Log back on the same day and repeat a few more times. The next day it will have some progress. And repeat this process for about a month or a few weeks. Remember to use bushes and flowers to line your path so your dirt paths don’t spread out thicker than you want it to. Hope that helps!
