Additional context
Add any other context about the problem here.

I am also getting this issue. Other materials, like starmetal seem to work fine, but rock crystals and celestial crystals do not seem to be able to be inserted into the grindstone.

Same issue with #163 but in different language
I am aware of this issue but I can't seem to get any useful info to fix it. Without any info fixing it is almost impossible, if anyone might have a clue about it please let me know

The most related thing to this is that I added an ore dictionary entry to the rock crystals in version 1.34.0, but the issue persists after I removed it

Were any grindstone recipes changed?

Nope

Solution: edit config\unidict\IntegrationModule.cfg and change B:AstralSorcery=true to false
Consequence of changing this is unknown, it might be a wise choice to wait till unidict releases an update that patches this and update unidict
I'm reporting this to unidict
