So i went to go look at the prismatic matrix to see the sunbreaker ornament in this week (really want it for the osiris look) yet its shaded out as if i already owned it. don't know if this is a bug so thought i'd put it here to see if anyone else was having a similar problem.
Exactly the same thing happened to me on a warlock with open mod spaces! Maybe it will be resolved next time I check ??
That simply means you were on a character that can’t equip it.
there is no checkmark so it is not showing you have it. were you on your warlock when you viewed it?
