[2.1.7] Asteroid signal no longer sets crushing recipe

[cellularmitosis]

Previously, to set the recipe for ice crushing, you could send one of three signals to a crusher:

• Ice Crushing
• Ice
• Oxide Asteroid

As of 2.1.7, that list is now:

• Ice Crushing
• Ice

This is a bummer, because previously I could do recipe switching without using any combinators, like this ice / carbon platform:

Honestly, it's a bit weird that it worked at all because there's not only one recipe for the crusher for oxide asteroid chunks, so the signal is not unambiguous.
Did you research asteroid reprocessing in the meantime?

This was an intentional change. Assembler's set recipe is supposed to select a recipe that produces given item, and given those recipes do not produce asteroid chunks (they produce less than they consume) the recipes are not selected.

Thanks for clarifying.

Could the crusher be made to ignore signals that do not represent unambiguous recipes it can craft?

As of 2.1.14, metallic chunk and oxide chunk set recipe to carbonic reprocessing. Carbonic chunk maps to metallic reprocessing. No chunk maps to oxide reprocessing. Was this specific behavior also intentional? It seems unintuitive, especially given the previous behavior.

Setting filters for collectors and recipes for crushers on the same wire would be a useful possibility. Currently "collect more chunks, but don't reprocess anything" seems unrepresentable.
