Sorry, that's because the mod intends to make it possible to use higher quality ingredients in both the vanilla and any modded rocket silos. (and just changing fixed_quality doesn't work) I didn't expect that another mod would rely on the fixed_recipe variable since the vanilla rocket silo doesn't and since there's usually only one recipe. I can make the fixed_recipe and fixed_quality changes opt-out and blacklist the relevant rocket silo from those changes.
Thank you for appreciating the mod as well!
