[1.2.1] Crystalline Old Forest can break vaults

[Waladil]

This has been reported before, I know, but it was an old bug and I wanted to re-report because it's still happening as of 1.2.1



I want my stuff, yo... and there's no door. The crystals are marked as diggable, but digging them doesn't actually do anything aside from take 13 turns. In fact, NONE of the crystals in old forest can be dug out, despite having the diggable tag.

So two bugs, really.
1.) crystals can replace vault doors
2.) crystals can't be dug.
