Expected Behavior

The machine should process the recipe.

Actual Behavior

It doesn't start.

Steps to Reproduce

• Put copper in a wiremill on circuit 1.

Additional Information

I have tried both ghost circuit and real circuit item, singleblock and multiblock machines. Recipes with other nonconsumable items like extruder molds still work.

Logs (there are some errors, not sure if related): https://mclo.gs/GXFMo7q

Still present in 7.0.2 release.

We hope it will be fixed soon

Still present in the 7.1.0 snapshot from 5 hours ago. Also I was able to repro with just gtceum and no other mods. Here is the log, if it helps: https://mclo.gs/GXFMo7q

Still present in 7.1.0-SNAPSHOT-03a3296.
It seems that all ingredents that are neither tag nor single item are unable to match any more. com.gregtechceu.gtceu.api.recipe.lookup.ingredient.MapIngredientTypeManager#getFrom only creates tag ingredient and single item ingredient from item stack, which means AbstractMapIngredient from programmed circuit item stack can never equal to AbstractMapIngredient from programmed circuit ingredient.

I fix it by this

modEventBus.addListener((FMLCommonSetupEvent event) -> {
    event.enqueueWork(() -> {
        MapIngredientTypeManager.registerMapIngredient(IntCircuitIngredient.class, custom -> List.of(new ItemStackMapIngredient(GTItems.PROGRAMMED_CIRCUIT.asStack(), custom.toVanilla())));
    });
});

Fixed in f51d89c snapshot
