I never would have tried to do the legendary solo campaign for the Lone Wolf chevo if I knew that there was a glitch that doesn’t give you the credit/achievement! I was so excited after grinding for weeks that I did it! When it didn’t come and then I found on forums that its glitched. ..well I wanted to cry.
Some peeps posted that it randomly popped up days or weeks later but I don’t want to wait. I want it now! I am 100% on the game and I want to see it.
