On mars, I had opened 2 sleeper nodes total and then it decided would not let me make override frequencies. This was not the bug, just me being dumb. I had to get a node in the ma'adim subterrane for a nascent dawn quest and then the combine prompt came up again. Although, when i tried to combine the resonant stems, it just consumed them and did nothing. I wasted like 8 stems and the game is just eating my stems for no reason. I don't know what to do, so pls help.
Known issue, you'll have to wait until Bungie patches it.
