I just noticed that this cool mod of yours doesn't have any effect on my Industrial Revolution 3 playthrough. Both your Dirt Path and Mining Scars are mods that are absolutely necessary for me. That's just how cool I think they are. Is it possible for you to somehow add support for modded miners?
I'm glad you like my mods! However, I'm not sure how Industrial Revolution blocks this mod. Mining Scars triggers on ore depletion, and has nothing to do with the actual mining drills used.
Thanks for explaining the way the mod works. I'm gonna have to scratch my head and think what else or what other mods could cause the lack of mining scars then.
