I got a Warlock chest piece from the Master Grasp of Avarice Dungeon, but it doesn't seem to recognize that I have artifact mods to apply to it? I got gauntlets in the same run and they work fine, but the chest piece doesn't allow me to apply artifact mods in any of the slots where you're normally allowed to. All the other mods show up, but the artifact mods just aren't an option to select. they aren't grayed out. The armor is masterworked. ???
