Was trying a beta pack that has the Mekanism mod 1.7.10-7.0.0.75 and noticed when using the Atomic Disassembler in vein mode it was ignoring redstone ore and only doing it one at a time.

So made a vanilla 1.7.10 with just the same Mekanism version and the same.
Don't know it this is intentional or just a little broke.

I bet this is broke, because when redstone ore detects a block update, it's form changes to "on" (so it emits light)

I am guessing what the atomic assembler does it mine all blocks you right click if they touch and have the same string/id, which in this case redstone ore doesn't.

Should be fixed
