I find it a bit odd that I can't use normal crushers from vanilla space age for this, especially since Mulana mod allows them to built pretty much everywhere. We have compatibility for every other mod crusher in the options but not the vanilla one, is there a reason for this or is the vanilla crusher just too difficult to try and add new recipes to it?

I do have Automated Crushers installed which adds psuedo-furnace style crushers and they work based on what gets input into it, I just find it a bit odd I have to use an Assembler in the base game to crush asteroids when the vanilla crusher is literally right there staring at me (menacingly)

how did you get the mod to work? i cant seem to get the chunks back, it seems to not work for me

Because I do not own space age and thus can't add or test anything space age specific. If I have time I'll add in a new option to just type in the category name to use so it can support anything, but it's not a priority.
