A hotfix, Destiny update 2.4.1.1 is now live on PlayStation 4 and Xbox One. Since it’s a hotfix, you’ll only need to download a small file (about 500KB on PS4), and you’ll need to log in to Destiny again after returning to the title screen to install the patch.
You won’t be removed from activities to get the hotfix yet, but if you haven’t installed today’s update by 2pm PT/5pm ET, Bungie will remove you from activities and return you to the title screen. If you want to participate in Iron Banner (Control), which begins at 10am PT/1pm ET, it looks like you’ll need the hotfix.
Designed to improve the quality of life in Destiny: Rise of Iron, here’s what changed with today’s hotfix:
Activities

Fixed an issue where The Taken Archon Priest in the Winter’s Run Strike was not dropping Skeleton Keys at the intended rate
