only played one round (which lasted about 3 hours NvN)
noticed 2 things.
Somehow SBH was stuck looking half stealth ed. while firing, half stealth disappeared but when standing still, character looked as shown. (1st person showed normal skin) Couldn't confirm if others saw or was just client side.
2nd after spawning as new Flame thrower infantry, his head was stuck tilted towards the sky, until I fired flame thrower, then he readjusted.
