I have Destiny on Xbox 360. After a day of lots of glitching, I logged in and my Zombie Apocalypse gun was gone. I did not dismantle, it just disappeared! It was one of my main guns and I spent my resources on leveling it up. All I needed was 2 more damage icons to be done and it would have been fully maxed out! Where did my gun go??? How does it just vanish? Is there anything I can do?
