Yeah it was weird. I was watching Voodoo running for the reinforcement station and we both saw the red glowing OWLF recording sitting on the table right next to it. He picked it up, then a few seconds later I spawned in and it was still there, so I grabbed it too.
Then after a very sweaty match we both managed to make it out, only I got no trophy pop and the game froze for a good few seconds when I went to the collectibles menu to see if I had it. When it eventually loaded, everything was still locked.
I thought it was weird that I was able to pick it up too since RidgeTop had said they weren't like the veritanium and could only be picked up by one person, so like Voodoo said it was likely a glitch to do with the respawning.
But on the plus side at least now I know what to look for!
