So I play on the Steam version of Destiny 2, and I'm a bit of a completionist. I've been going through and trying to get all of the achievements, however, I've hit a bug of some kind with Zavala's Lieutenant. The achievement requires you to unlock every subclass for the Titan, however, it seemingly has not triggered the flag for unlocking after doing so. I even went ahead and played through the entire Beyond Light campaign just to make sure it wasn't including Stasis since the Steam Achievements are pretty much locked to Forsaken content. Still no luck. I have the equivalent achievements for Warlock and Hunter, so I'm just puzzled as to why I can't unlock the one for Titan. Google searches have only shown me Xbox players who have had this problem, for them the solution was to switch profiles but that's not something you can really do on PC, I am at a loss and would greatly appreciate any advice/help.
