I noticed a connection between the two. Not sure how to post screenshots, but when playing Iron Banner, I sometimes noticed my artifact contributing to my light level. When right clicking my name, it shows I am in orbit, NOT in Iron Banner. Also, when this bug was active, I was not getting quest progression (bounty or quest step) likely because it doesn't think I am in Iron Banner. I was stuck at 99% for the Rout with this bug from beginning of the match to the end. Quitting the match then starting Iron Banner from orbit did not fix it. Instead, I needed to load into another space (the tower) and then load up Iron Banner again to fix. Hopefully this helps! Have a great day and keep up the hard work.
