The new patch released tonight (23/4) worked for me. I've finally got the Platinum. It just didn't popped right away. I was in freeplay and used one legendary light machine gun (lmg was one of my glitched trophies). After a few kills it popped. Surprised I changed to a masterwork Heavy Pistol (also glitched trophy) and it also popped after a few kills. So long as you use one random weapon in the glitched trophy category it works.
