I am creating a block breaking task that tracks when any stone block has been mined. (since stats only records one at a time or I would do a scoreboard tracking) Anyway, using CraftTweaker, I created a ore dictionary which included stone, diorite, andesite, sandstone, granite, netherrack and endstone. All the blocks in the ore dictionary show up in the picture for the quest, however, only the stone, diorite, andesite and granite register as broken and advance the task number. Its even worse if I do ores, only Iron is recognized as broken.

To Add a little more investigation: as the block id I listed minecraft:iron_ore then in the ore dict slot I put my custom ore dict: all_ores. Now, it cycled through the pictures for all the ores in my ore dict, but only recognized iron when it broke. In the case with the stone, I think its because andesite, granite and diorite all begin with stone in their ore dicts so again recognizing only the block ID and not all blocks of the same ore-dict.
