How do you fix bugs?

i found a bug in borderlands 2 handsome collection and i have no clue how to fix it. half my weapons are disappearing from my inventory and if i go to sell it it is still there but when i check my inventory again its gone. is there any way to fix this?

Did you accidentally change the sort type in your backpack? You may have changed it to show only items, which is why your guns aren’t appearing.

actually guns are the only thing that appears everything else doesnt, like the head or body customizations or relics or even shields does not appear but guns do

nevermind you were right, i accidentally changed it to types in my backpack and those things wouldnt show up for types, thank you lol i feel dumb

Glad you got it figured out. Happy hunting!
