Can you release or add block id's to wiki? I'm having difficulty adding blocks such as overgrown netherrack and mycelium netherrack. I've tried to guess id's such as:
Biomesoplenty:overgrown_netherrack
Biomesoplenty:overgrown_nether_rack
Biomesoplenty:netherrack_1
Biomesoplenty:netherrack_1/2 (3,4,5,etc.)

Biomes o' plenty: 7.0.1.2394
Vein Miner: 0.38.2
Forge: 14.23.4.2725

Use F3 + H in-game to turn on debug tooltips that will show the blockstate of a block, or just hit F3 to turn on the debug overlay and look at the block you want to know info about and it will show on the right side.

What you are looking for is: biomesoplenty:grass, variant: overgrown_netherrack, which has the meta value: 6.
