Talking to Josh from The Bit Block:
regrowing grass is easier, when it snows / rains you will see it regrow.
also if you plant flowers in dirt and then water them the next day you will notice a difference in grass growth
it seems to die off in areas you dont even walk lol
i have been taking snapshots since last night and i'm going to show it regrowing over the course of a week
but.. it definitely seems to be easier to regrow it and harder to kill it
So, that's cool to hear.
Hmmm I wounder if the Beautiful Rule makes it impossible to kill? Also anyone know what the New and Late Rules do?
