Apparently, Refined Storage can’t handle both dust to ingot and ingot to block recipes.

@way2muchnoise we should really make a wiki article on this message, people keep asking about it

The problem is that you have a loop. 9 Iron Ingots can be made from 1 Iron Block, and 1 Iron Block is made from 9 Iron Ingots; and/or you have 1 Iron Ingot can be made by smelting 1 Iron Dust, which can be made by crushing 1 Iron Ingot.

You can fix this by removing any of your two-way recipes. They are usually redundant (why would you need to know how to craft ingots from blocks if you are storing ingots?)

Also, please search before opening a new issue.

@PapiDimmi why are you downvoting his explanation?

Because I disagree that it’s redundant.

I'm having this problem as well. My issue is stuff like inferium, which can be converted back and forth depending on what is needed.
