It has been months since I've seen any Resonate Stems drop for any of my characters. I've done every activity I can think of on Mars and still nothing. Patrols, world chests, powerful enemy chests, adventures, story missions, lost sectors, escalation protocol...nothing is dropping these Stems anymore. I'm trying to grind for Frigid Jackal so I can get my Wayfarer Seal, but the only method I know of getting the Braytech weapons is from sleeper schematics...via RNG from the Sleeper Nodes. With no more Resonate Stems, I can't do anymore Sleeper Nodes. My question I guess is, is anyone else experiencing the same lack of Resonate Stems dropping from Mars activities? Also, is anyone else aware of other methods to obtain Braytech weapons?
