[b]TLDR;[/b] 1 newly earned lost memory fragment disappeared from my inventory and 3 lost memory fragments from season 12 disappeared from my vault sometime between 02:00 and 20:30 CET February 13. [b]Full[/b] Last night I completed one of (two) weekly Gambit fragment quests from the stranger and thus received a lost memory fragment. I didn't bother to "buy" a fragment from the stranger as I wanted to research which to select first and come back later. When I log in today I discover that my lost memory fragment has disappeared from my inventory and I'm no longer able to acquire my first new fragment from the stranger(!) Have anyone else observed this? Is this a known issue? I was grinding Gambit hard yesterday to acquire this so this is not awesome. Side note that may be relevant to my issue: during season 12 I acquired too many lost memory fragments which resulted in me having 3 spare fragments stored in my vault (not inventory). Out of curiosity I checked my vault in DIM last night (after logging off) and sure enough they were still there. I fond this to be strange as Bungie clearly stated that these were going to be removed during transition to season 13. These are also gone when I check my vault now. Which ofc is ok by me :-)
