Placed Gneiss Cobblestone not detected as such by wand of equal trade

[Xaroth]

When using a wand of equal trade (thaumcraft 3), targeting gneiss cobblestone; it detects it as being a cobblestone; but it does not recognise the fact I have 27 stacks of it in my inventory (whereas with other placeable blocks it does)

Versions used:

Thaumcraft3.0.5e UndergroundBiomes 1.5.x - 0.4.1

That's because placed stone has different metadata from world generated stone and stone kept in the inventory.

If you get oak leaves using shears, then place one in the world, pick it with the wand of equal trade and try to use the wand on something, it won't work, similarly because placed leaves metadata is different, so placed leaves won't decay.

In Underground Biomes, metadata is used to prevent farming rare drops.from placed blocks.

Thaumcraft equal trade wand should call block pick function to get proper metadata. Not my area to fix.

I could make cobblestone and bricks metadata not change, but smooth stone will still need it and so will keep this effect.
