Im currently building a modpack for 1.10.2.
Now i would like a to add a compressed version of enderio's electrical steel block.
but if i type in your config:

enderio:blockElectricalSteel:8:true

nothing is happening.
I think it has to do with the programming code from enderio, because i think the blockID is:

enderio:blockIngotStorage:0

now my question is:
is it possible to specify metadata in your config option for compressed blocks?

Minecraft Version: 1.10.2

Overloaded Version: 0.0.17E

Metadata is not supported in old versions. I added that in 1.12 and currently do not plan to backdate that system.
