RS SL can't equip smoke after equip knee mortar

If you're a Squad Leader and use all your smoke grenades, if you equip a knee mortar, you can't switch to smoke again, even taking more on an ammo box. You can try changing to another weapon or dropping the knee mortar, but you won't equip smoke no more. I realize this bug a long time ago and again today. I don't know if it was reported here yet neither if it happened with someone else, as well.



Can anyone confirm it for me?
