Both the tin and copper drawers are using oreberries, all the other metals are nuggets. I only inserted ingots into the compactors.

Are you on 1.5.15?

Yes. Using latest version on curseforge.

Those both look like Tinkers ingots, so it's actually a valid match to pull up oreberries while still trying to enforce a match from the same mod.

I think this is happening because you also have Thermal Foundation, which introduces oredictionary-based recipes (oreberries can be crafted into TE ingots). All these recipes get pulled into a candidate pool, and then the first one that is a same-mod match gets picked. Oreberries must be listed first in this case.

This can be worked around by populating the drawers with the nugget first, or by registering the nugget/ingot association with MineTweaker, which will bypass the lookup machinery.

Ah, thank you. I will try the nugget approach first. Haven't tinkered with Minetweaker yet, so behind on the learning curve there.
