"Unstoppable Force" M4A1 variant does not save attachment changes.

On the PSR unstoppable force version, if you unequip the red laser, it will simply re-equip itself whenever you enter or exit a match. This bug isn't observable on the regular or warfighter variants as far as I am aware.  It will unequip the last equipped attachment to make room for the red laser in your attachment points allotment. I have attached a video showing the bug: entering a match and exiting, to show it applies to both cases. I'm unsure whether it applies to more cases simply because it already occurs so frequently.
