This is now happening for me on items I'm getting from Bloodstone Fen master. I have four of the items so far and I can't salvage them; they're highlighted in red in my inventory when I open a salvage kit. I tried leaving the map and logging out and back in and they still won't salvage. Specifically, I have the Strange Residue, Rift Residue, Living Bloodstone, and Aged Ectoplasm so far
