I was playing with my friend in Washburne Refinery, we were massacring Hyperious over and over and my friend started getting serious loot lag. Trouble is, we both had full backpacks. So I dropped my four equipped guns, picked up 4 new ones, ran over and sold them from my equipped slots. Then I did it again. After the third time, I realized I had sold a weapon I wanted to show my friend, so I went and bought it back. No big deal. Except, the item didn’t immediately go to my equipped slot, it went to my backpack. So now I had +1 backpack space. I picked up 4 more random weps and swapped one of them to the Hornet I had wanted to show him, and boom, it was a real weapon slot now. (Simply moving the item straight from my backpack to an equipped slot would have removed the extra slot). Long story short, this is an infinite backpack glitch, presuming you have an infinite supply of weapons, coms, shields, and relics to keep filling your 8 equipped slots with.
Good news: Backpacks are stable up to 500 items in your backpack and 8 equipped, and probably goes further, I didn’t take it past that.
Other good news: This does not affect load times (at least for me).
Bad news: If you do this the way I did it, you will lose money, I think due to Seraph sell/buyback values. I lost about 30million while adding 300 new backpack slots.
Has this been known about for a while, or did I just find something new and cool? I don’t know how often people sell and buyback their equipped items.
