I couldn't craft in the solid field assembly machine - automated package!

Hiya, sorry I don't follow what the compatibility issue is, can you elaborate?

I couldn't make the automated research package in the solid-fuel assembly machine (tier 0 mod AAI industry), only in the Assembly machine tier 2.

Oh that is not a bug with Alloy Smelting, which does not touch the Automated science pack recipe at all. I'm looking at automated science pack and it's craftable in the burner assembler just fine. That is a compatibility issue between AAI Industry and Nuclear Science please report the compatibility issue over there :)
