The House Meyrin shader from Gofannon Forge dropped once for me way back when it first came out. Dropped once on a weapon and when I dismantled it to get the shader it didn't give it to me. I've been grinding Gofannon on and off since then trying to get it. It's the last item I need to get the Annual Pass Black Armory badge. After more than a year and a half it still won't drop. The ghost drops nearly every time I run the forge, but no Meyrin shader. I'm running the gold weapon bounties, hand cannon and sniper rifle, polymerized, and still nothing. Bungie, what gives? What do I have to do?
