It only seems to be some items. The Moon Disc shield I got the other day I just copied into GDStash, exited and then went in to search for it and it showed up. But the helmet and amulet don’t, even though they’ve also been added to the Stash. None of those green items can be found, only the blue shield shows up. I don’t have any other blue items with 2 masteries on them in there so can’t check if that’s an anomoly or all blue items are fine.
