Quark andesite/diorite/granite bricks don't play nicely with chisel. They can't be chiseled into or out of.
This may be related to a chisel bug where these stone types can be swapped or turned into smooth stone, but not turned into their chisel variants (Chisel-Team/Chisel#280). I'm hoping the solution for one may fix both. Thanks.
Edit: The chisel bug was the result of Dark Utils oredicting decorative stone with smooth stone. Apparently, Quark just needs to identify the decorative blocks with chisel, if you want.

Closing because I'm cleaning up the issues page. This issue is really old and probably irrelevant. If you feel i should be re-opened please tell me why.
