Have you had this?

So I was playing WAW on my PS3, sometimes weird things happen like jumping up in the air and floating, running fast and stuff. But the weirdist thing happen when gamer tags were biger, hard to kill enemie players (Even though they can kill you.), the Default Weapon was there, but what got me was I was rank 65! I had all the weapons and perks! I thought to would go amway and went to play a Free-For-All and my Sawed-Off Double-barreled shotgun had a red dot sight! I tryed to see if it was just PSN by checking the ohter user's PSN and turned out be it was just mine! So, have you had this and will it go away?
