I picked up over 100 rocket souvenirs, they have zero weight and supposedly have a value of 3. I completed the quest that required 5 of them at the rocket test facility and the souvenir's are now stuck in my inventory, i can't sell or drop them.

The same thing is happening to me and my brother. We have separate PS3's and game save files so it's probably something wrong with the item itself.

I picked up 100 of them and I can't see them anywhere in my inventory at all!
