I have lost loot in such a fashion as well... nothing approaching twenty min... but on the order of 5-10.
You know... group wasn't gonna wait for me to pick up my loot before heading off to the last group do did that first and literally watched it disappear.
Meh, was just gonna be some vendor trash but... still.
I was just on a 5th order of exploration and I had a large pod drop on a ground mission.
After dying i ran back immediately and saw the pod... after about 2-3 mins it disappeared.
Total time was probably 7 minutes and it was gone.
I have had this happen to me too - in space and on the ground.
I think they should just let us have AUTOLOOT. It's my loot, just put it in my inventory. Thank you.
All the frantic running around after aux batteries is stupid. The only reason I even stop for the junk is because sometimes it actually is something good... that I needed five levels ago, and have no use for now.
The loot is crap, and there is not enough of it... and then they even fix it so you can't pick it up. Real nice.
