I like how well this mod plays alongside AAI Industry. I wonder why it isn't listed as an optional dependency?
Anyway, there are still a couple hiccups I've noticed, mostly with the recipes of the crushers themselves: The Electric Crusher does not require a Burner Crusher as it should, nor do the Burner Crusher and Electric Crusher require Single-Cylinder Engines and Small Electric Motors, respectively; The same as other buildings of their respective tiers. The Big Crusher & Space Crusher recipes seem fine.

Also, any building with Concrete in it's recipe has the requirement replaced with Concrete Mix if it is enabled; Not sure if this is intentional.

Hiya! I've updated the burner crusher to use motors instead of iron gear wheels. I haven't updated the electric crusher yet, but only because I haven't come up with a solution I'm entirely happy with yet when AAI Industry is installed. As for concrete mix, yes that is intended behavior. There are a few recipes that are intentionally not modified to maintain progression on other planets (e.g. recyclers, since otherwise you couldn't craft them by hand when you land on Fulgora), but it's done to encourage more unique base designs :)

I would suggest changing the Electric Crusher's recipe to 8x Steel, 2x Green Circuits, 4x Small Electric Motors, and 1x Burner Crusher. That way, the total resource cost (8x Steel, 30x Iron, 15x Copper, 11x Stone) would be more balanced AND only slightly higher than that of a tier 2 Assembler (2x Steel, x28 Iron, x12 Copper, x9 Stone); Likewise to the new Burner Crusher (18x Iron, 10x Stone) being only slightly more than that of a Burner Assembler (11x Iron, 8 Stone).
I would also suggest moving the unlock of the Electric Crusher itself to the Ore Crushing research, replacing the Multi-Cylinder Engine prerequisite with Electronics. (The current Electric Crusher can be researched WITHOUT the E. Circuits necessary to make it)

I've made my own personal update to the mod with the changes I suggested above; The only thing I haven't decided is where to move the Electric Crusher research unlock if Ore Crushing is disabled in the settings. I can add you on discord, if you want to check this out?
