Q: How can i get different numbers?
A: Change the random seed in the mod options.

Q: Recipes still use the same ingredients, just in a different amount. What's going on?
A: This mod is working as intended. It does not randomize which ingredients go into a recipe, only how many. If you want to randomize what kind of ingredients are used (for example, needing assembling machines to craft nuclear reactors), there are other mods for that.

Q: How can i disable that certain things get randomized / only randomize certain things?
A: Use the randomization mode "Custom", check all individual properties you want to randomize and uncheck all you don't want.
