My niece loves LBP3, she was able to play story mode with her sackboy just fine but recently she was unable to even use her sackboy, her other characters are fine but its just the sackboy. when she tried to get on it, the sackboy would float and and fly to the left and die, making the pod move left and right until you restarted(in her pod). in creation mode when shes on her sackboy it flies up while spamming/vibrating up and down, then stops then falls down to the left and dies. i've tried to restart the game, her profile, i've tried other LBP forums to see similar problems, and i've tried youtube video guides but its not working.
PLEASE help! i really want this fix so my nice can get back on LBP and have fun!
