Same Weapon in the weapon crate help

[jtwepiczombie]

 I made this post when i opened a crate and got a SCAR however i already had one and i thought i lost the second one completely, However i know if this happens to you just sell the weapon and relog. You then get the other weapons sell tokens and you still keep your original one. This will only work if you open a crate and you get the same weapon as you have brought before and that you have it in your inventory. Thanks to @Wiggles for telling me about this.
