This is for 1.8.9, latest everything. It seems expression parsing for block name does not work. If block name contains both colon ":" and underbar "_", then the name is not parsed correctly. For instance "//count minecraft:clay" is fine, but "//count minecraft:hardened_clay" is not. Of course, with vanilla blocks it is easy to remove namespace prefix to use "hardened_clay" and it works, but with other mods that is not possible. I took tinkers construct mod and name like ""tconstruct:firewood" works fine, but any name with underbar in it doesn't, example "tconstruct:stone_ladder". Same for biomes o'plenty. Names like "biomesoplenty:mud" works but any name with underbar doesn't, example "biomesoplenty:log_1".
