As you can see, using the blast chiller to create digits and operators is 1000x more expensive than using a casting table.
I had been using the blast chiller the whole time since I assumed the recipes costs were the same without looking too deep into it and because the blast chiller was a more advanced piece of machinery than a smeltery. I only noticed when I realized how insane the grind would be to finish the pack.

The version is 1.3, and it is still the current version on curseforge. Same issue as #264 .
