I don't know if this is either "LB' or "LP" that is causing the issue. I tried here first since its 2 pipes that I am using is from "LB".

I am calling for an Item that as 2 steps in its crafting with the same machine. You will see in the set pics what it dose.
It seems that the crafting manager dose not call for the item that was crafted back for the 2nd step.
I also looked everywhere in github for this same issue and nothing came up.

Pictures Of Issue

I apologize in advance if this is not the mod that is causing issue.
I also apologize in advance if I am a complete moron and I am just doing something wrong.
Thank You for your time.
Also if you need me to post pics on here I can do that instead.

The items were being pushed into the pipes and the pipes were thinking that the item need to be sorted. So finding away that the pipes can pull the item that it is seeking to cont. their crafting.
