I unlocked the "Suppressing Glaive" mod in the artifact, applied it to my class item and played for a while. Then I logged in again today and I didn't have it but I had a point to get it. I tried to unlock it again but when I unlock it it's greyed out (see the image).
How can I get support for this?
I had the same question earlier today.
Bungie tweeted about it earlier today.
Originally it was only goi g to be disabled in the day one raid. But they found an issue with it and have disabled it everywhere for the time being. They did not elaborate on the issue.
General consensus is that hunters using it could be perma invisible using melee kills
