Uses 10/10/10 of processing unit/low density structure/rocket fuel in Space age, rather then the 1/1/1 of Space Age for a rocket part. It still gives the 2% progress, meaning 50 booster parts are needed, but the cost is 10x higher than Space Age. Even with the recover of 25% chance to recover, that's more material cost then without the mod.

Also no way in settings to adjust anything regarding this mod.

Thank you for the report,
Yes, the bug was the recipe not applied to the Space Age so it kept as vanilla 10/10/10.

As for mod settings, actually the mod have only one refund chance value (that 25%) that can be made adjustable, but I deliberately keep it low but not so harsh (at 25%). The goal is to not create infinite resources loophole which kind of ruining the fun, don't worry if you can push the productivity to the game's cap +300% you'll break even with 25% of the mod.
Fixes are up,
Cheers.
