Hello,
i had 22 Rockstar Energy Codes on my Battle.net Account.
I have sent them to my Destiny 2 Ingame Account.
12 of them Disappeared at them momemt i transfered them from the Postmaster to my inventory.
10 of them worked correctly.
The Blue Engrams are not a big deal, but the Codes cost real Money, and i want to use them for my 2nd and 3rd character.
At least one of 22 Engrams disappeared from my girlfriends account, too.
