First off I just want to say that the change in loot in mission treasure chests, with nano rechargers and treatment kits appearing in much greater frequency, is great! I am always happy to find these things. Now when I team with people on my doctor the team will usually let me have the nano rechargers, and I don't have to feel like I'm spending way more than everyone else on my hunting equipment.
There is only one problem. The kits that I find won't stack with each other, even ones of the same QL! Now I have backpacks full of bundles of nano rechargers and treatment kits. My bank may explode soon! Please make these things stackable, the way you can stack the first aid kits of the same QL.
