I've noticed that before install space galore when I put carbon signal for a defining a recipe in the crusher It used to gave me Carbonic Asteroid crushing, Now It prioritize coal crushing instead and broke some of my circuits for spaceships
Unfortunately, I cannot fix this as this is a limitation by the factorio modding API. You transform the item signal to a recipe signal using an arithmetic combinator using a *1 operation. Thanks for the bugreport nevertheless. :D
