So I bought a 5 pack of Heavy ammo synthesis from Eris today and then did a pair of strikes (seriously, two). Returned to the tower and saw that 5 had become 1. So what the hell? Do they just disappear over time or what? This isn't the first time this has happened to me either, so I really want to know if it's broken or intentional. I'm playing on PS4 - Digital Guardian Edition with the Dark Below installed(obviously) and latest updates.
