So I read a thread somewhere that stated a player with less items in their backpack had a better chance of "finding" items. I had many duplicates so I figured I'd try it out. I already had the Axtinguisher and the Flare Gun since the Pyro update, so I deleted them, the ones that I "found" since the update. Turns out, if you delete a "found" item from your backpack, it deletes it permanently from load out, that includes the ancient ones that you may have had since Medic/Pyro updates. I thought I was deleting my "found" duplicate, but apparently it also deleted two of my Pyro items. Just a heads up.
