I thought it would be cool to see scarring over the patches that had been mined up, but I'm noticing that the scarring is just being spawned randomly around the drills. Densely packed forests are turning into scarred ground where it just doesn't make sense for that to be happening.

Mining is dirty and affects more than just the direct tile the ore is on! Scars are weighted to happen close to the ore but not always. It's also a progression, so tiles have to be hit multiple times to really show the effects.

There's room for tweaking the values but I like how it looks.
