I know this is not a vital issue, but some Steam achievements are not working correctly. As for now for me it would be: - "Show Me What You Got" (completing "Light reforged" quest), - "High-Stakes Play" (win a Gambit match), - "Legends Grow" (earn 5000 triumph points) - and maybe "Seal the Deal" (complete a triumph seal), as I've completed two title seals, but not a triumph seal, I don't know if it counts. There was no problem with completing a Nightfall strike, acquiring subclasses, getting Red War exotics and some more, but the ones above did'n unlock even though I completed them (even several times, like Gambit matches).
