Twice I've had a scry I discovered from a lockbox in Reaper's March not go into my list to scry. I saw it in the loot window, it said it was now available to scry, but when I pulled up my Antiquarian character that has it maxed to 10 it wasn't there. It was the gold lead for the mirror. I did find it yet again and this time it finally went in my scryable list. But twice it did not. I reloaded, relogged, restarted the game, shut off all addons, nope, not there twice. I even took a screenshot the second time of the loot window showing it WAS there.
