All right, after testing for a few minutes I was finally able to replicate the movement bug. It seems like if you press left and right on the joystick and only on the joystick too fast it'll send you flying one direction. As to the aiming one, I'm not sure I've been able to replicate it fully, but I found that if you press the aim key for too long it'll change your aim as if you had pressed it again. Thanks again for reporting as I'm not sure I would be able to spot this otherwise.
