So, this morning, I spent over an hour on the Moon. Killing stuff. Opening boxes/crates. Running side missions. Generally, just goofing around, having a blast, while gathering the HECK out of Helium. I've been doing this on each planet preparing for major upgrades on new gear. So, I get back to the Tower to admire my gatherings only to find TWO (2!!) additional helium parts added to my inventory. WHAT THE HELL!?!?! Bungie, how about checking into this and giving my rightly earned helium back?
