Standing in CA HQ as i was running tl150 missions. Had 2x the mission items in my inventory for tl150 res missions. I had yellow weight and decided to toss the items on the ground from my inventory. At this point they duplicated and became 10 mission items. It was like i received 8 more from no where.

I then tried to throw the 10 items on the ground. they fell in 2 piles. a stack of 2x and a stack of 8x. they were data cubes. i picked them up and i had data cubes in my inventory. Im not sure if originally i had 33 cubes on me or not.
