Yeah, I'm trying to see if more people comment if it works or not for them, because someone recently said it worked for them, but not for me. I'll keep looking for more ways if they're not patched. Most are tho.
I don't know if it's really an explanation besides it being a glitch. I put in the description that I wasn't sure if it would work for everyone. It also didn't work for my Nephew. But try and sell your unclaimed property items and see if any weapons stay in your locker after you've sold them.
