Forum:Skill Point as a Drop?!?

I entered an Xbox Live game once with Lv 61's (I am too) on Gen Knoxx, and they were were farming C-max. When I walked in, I saw a pile of skill points on the ground. I picked up two or three, and sure as shit, I had new skill points to spend. I entered my skill tree to allocate them and realized that, like always, Xbox Live didn't choose the only character that I have created, and I had was using a Lv 1 Roland, fresh off the fucking bus. BALLS.

I haven't seen anything like this since, but I'm positive that I saw what I saw. Anyone know how? Obviously modded and/or duped. Could it have been the reward from Moxxxi's Underground rounds duped or something? Are those backpack items?

Thanks in advance.
