Magmatic Ore vendor talent bug(poor wording?)

Hi,

So the talent on weapons that says "Item sells for an additional Magmatic Ore" doesn't work, at least not with 6socket items, the vendor only offers the Magmatic Ore and nothing else.

Either the wording is poor, and should be "Item sells for a Magmatic Ore", or the mechanic of adding the orb breaks 'normal' vendoring outcomes.

Of course I'm not worried about missing out on a few jeweler orbs, lol, but I'm thinking weapons with the "Item sells for much more to vendors" might provide some players with really massive disappointments through this bug / poor wording, where the result before-crucible-tree might be nice, and then adding the tree and working it up to add the "additional" magmatic orb then bricks the original trade despite the wording clearly indicating it should not.
