I had this happen to me twice in Iron Banner this weekend, once while I was on my Xbox One and saved the video. It's hilarious because I now have an epic fail video, but at the moment I was so pissed! In such a close match, why now? We were there, "Heavy Ammo Available" was announced, and like usual I picked it up and ran to slay some enemies on Zone C, only to realize I had no heavy when I pulled the trigger and quickly died. I'm so use to it just popping in....fail. I blame myself for the epic fail death, but the ammo should have been in my weapon. Not only that, but the enemy swooped in, popped a bubble and THEN it decides to show up just in time for them to pick it up. How convenient. What the hell Bungie....what the hell? Anyone else run across this bug in Iron Banner?
