"Hey Elisa, have you noticed our town's barren as a desert?"
"Yep. Grass dies before they get to us."
"Why?"
"No idea. Grass seems to grow fine beyond our base, for some reason..."
Grass now spreads roughly ten times faster. Great if your grass dies before it gets to the middle of the map. Growth rates are unaffected.
