Changes flagstone, concrete, packed dirt, and paved tiles to accept less filth. Makes sense for the floors that have negative beauty, right? And nobody wants to be cleaning outdoors flagstone paths all the time.
Changes filth multiplier of the following:
Flagstone = 0.01
Concrete = 0.25
Paved Tile = 0.15
Packed Dirt = 0.10
Update to fix flagstone and packed dirt not being changed.
