I'm running DW20's pack and it did grind black quarts but for some reason this current version missed that addition, can someone tell me how to add Black Quarts to the SAG mill's ability to grind?
I think that was a mod update to EnderIO. Direwolf20 had the same problem in an earlier episode of his new Let's Play YouTube. The mod has already been fixed and will be in the next version if it isn't in the 1.1.3 beta version of the pack now.
