crusher selects unsignaled recipe (resolved, kinda, not really, but its a "feature")

[Rauschkind]

i have a crusher that frequently selects "metallic asteroid crushing" for a tick when switching between "no recipe" and "metallic asteroid reprocessing", throwing off my control logic and breaking my system.

i double, tripple and 10x checked if there was any combinator with that recipe which could interfere.
there is not. i have one combinator with that recipe, but the condition can not be met (condition is storage tank of copper filled and there is no copper consumer currently).
furthermore, the behaviour persists if i remove said combinator.
i installed a powerpole and connected it to the wires to see if there is a signal. there is none. however, i am not fast enough to visually detect a signal turning on for just one tick, not even on 1/4 speed.

i am trying to make sense of this for a very long time now and i start to think it must be a bug because there simply is nothing in my network that could give this singal.

edit: the issue is, that the machine interprets the signal "metallic asteroid chunk" as "metallic asteroic cruishing" which is just bad because these are just two different things and there are multiple recipes made from "metallic asteroid chunk".
i understand the difference between a feature and a bug, but i kindly ask to reclassify this one because it seems impossible to read the content of that machine without setting the recipe to nonsense.
