-dead grass block breaks instantly.
-some blocks don't have names:
block.moreblocksmod.sand_chiseled_stone_brick_mix
block.moreblocksmod.coarse_dirt_cobble_stone_mix_heavy
block.moreblocksmod.sand_stone_brick_mix_heavy

Can you make mixed dirt and stone generate naturally?

Fixed the names, it is now in the 0.1.2.0 Bata Update
The dead grass block will have the resistance and hardness adjusted for the next update

Its a good idea for it to generate naturally. My initial thought is that it would be a crafted block. As you probably have seen, I haven't done much with these blocks because I'm not sure how to implement them further. Any idea where I should have these generate?

Didn't want to open a new issue for this. Please use the proper versioning (like 0.1.2 or 1.2.0)
[main/WARN]: Mod moreblocksmod (0.1.2.0) uses more dot-separated version components than SemVer allows; support for this is currently not guaranteed.

Got it, thanks

Fixed for the next version
