I was trying to lab this and figure out if this was possible.
It comes down to: are loadouts saved on a server or on your xbox?
A friend of mine said his loadouts seemed to keep disappearing and he thought it could have something to do with the fact he had 3 different xboxes and the loadouts were saved on other xboxes.
I tried using multiple storage devices on my xbox to see if I could essentially have multiple versions of one gamertag saved so I could switch storage devices and instantly have 5 different loadouts, but I had zero success.
Anyone know if this is doable?
