Hey there Bungie! As you'll see in the linked video, I was awarded the 'Specialized Rampage' bounty for simply riding my sparrow. Sadly the first few seconds of the video were cut off as 'Xbox Record That' didn't respond on time, but I assure you that I was on that sparrow since the spawn of patrol. This has happened with a few other bounties but I don't recall the circumstances within. I just remember them unlocking for no reason. Hope this helps. Many thanks, Mark P.s. Nice to meet you folks at EGX!
