Hello, thanks :)
You will have a tech that does nothing now, except granting access to aquilo (the space-crushing) as all crushing recipe are hidden. (but i feel like it's not really in issue).
I didn't want to remove that tech as it's one required by a mod, so in the best scenario, the creator of Crushing Industry should take the time to adjust it for this use case.
In any case, it seems to works, i've checked the tech in game and it looks good and playable at least :)
