That's strange?

Continuing the discussion from Gearbox skin? xbox360:

I have it! It was in my skin inventory after an update. I actually have all kinds of skins and heads I never found on my own. they just appeared. like the snow man head and the turkey heads. if it’s not legitimate then why did i get them? Is this just another scenario of how buggy this game is? Keep in mind I love this game, I’m not being negative, just honest.

Some people did get the Gearbox skin due to a glitch with an update.
But the skin is still not obtainable via any loot source in the game. It is a common skin that is hacked in illegitimately. But those who got it via glitched update did not do anything wrong.
