Ok.... So im playing with a medium body type with an assault rifle. I finish the game, and change my body type to light.. I turn of my PS3 without exiting the game.. I log back on and enter a versus game.. And all of a sudden, i'm a light body type using an assault rifle. I even checked to see if I could wall jump and I could. I went to an outpost to check my weapon and the one I was currently using was not there, and no weapon there had that little dot to indicate that you were using it.
Also as a side bug, sometimes when I play versus and I am capturing an outpost in 3rd person, I look at my character and no appearance settings besides body type are correct. They are all random loadouts.
