Not receiving Credits from Duplicates in Loot boxes

Yep, the same thing has happened to me every day on PC over the past few weeks and I kept thinking I was imagining it until today! I always just assumed the game wasn't going to cheat you! Unfortunately I've just realized that it's been cheating me every day for the past few weeks out of both crafting parts and credits! I guess EA is upset about the "pay to win" debacle and now it's just trying to cheat its customers in a different way?
