So I had found a legendary SMG, Hefty Baby Maker, req. 19. I've been using it for a while now, mostly because the reload/throw does a buttload of damage.
Something weird just happened though.
I opened up my inventory after a pretty big firefight, and I see another Hefty Baby Maker sitting there, this one req. 25, with way better stats minus fire damage. I'm level 27. I still have both guns, the 19 and the 25. I don't remember picking up anything orange during the fight. Google tells me nothing about Legendaries upgrading themselves, and I refuse to believe I got the exact same rare drop and didn't notice picking it up.
Did the game bug out somehow? Or, do legendaries level up along with you if you use them a lot? Or, did I inadvertently dupe my gun (even though the properties are different) and scale it up to my current level?
Any help would be appreciated.
