It is hard enough to have to redo this mission over and over to try and get the Chatterbox Creative Mag, but now I have done it a total of 3 times over the past 72 hours (2 hard, 1 challenging), and none of the crates in the mission reset (everything opens but is empty). I get they don't want us "over-farming" stuff, but I am getting tired of wasting keys on Hyena boxes that don't drop ANYTHING, not even golds/purples. I already have the other 2 pieces for the build, and know where to get the blueprint after I have all 3 pieces, just is super annoying to do the mission that is supposed to give me a chance to have this gun, but nothing comes out of the hyena or normal crate drops at all.
Also, what's up with the severe lack of specialty ammo all of a sudden? I've completed 2.5 of maxing out my specialty guns (100% on grenade launcher and crossbow), but I'm now on the sniper and it is 100% worthless as I never have any ammo and am lucky if I get 1 piece of ammo in 2 or 3 missions. I basically forget that I have it because it never has any ammo. Again, I get wanting to "limit" the use of it to key bosses or elites off in the distance, but if I never have any ammo, why even have it in the game?
Don't mind the grind, don't mind the randomness, just don't think these 2 components are working as they were meant to at the moment.
Believe chests reset 24 hours after when you open then. If you open them again before the timer expires then it refreshes said timer, even if it's empty, hence why you're seeing empty boxes. Not ideal for sure. They have however mentioned in the state of the game that they're looking into streamlining the reset timers on boxes, hopefully so they reset at a static time each day.
They've also mentioned specialty ammo is also a little wonky right now and they're hopefully going to fix it in a patch after maintenance later.
