Can't swap items in Firestorm on PS4
What's wrong with grenade and gadget swapping on PS4? It seems I can't swap them. I navigate to the item in the backpack I want to place in "active" slot, press X, then navigate to the item I want to swap with in that "active" slot, press X again and nothing happens, just sometimes my character stands up from porne/crouch. Yes, I am aware that grenades can only be swaped with grenades and same with gadgets. It only works when I swap item from backpack with empty "active" slot, so I am forced always to drop something on the ground to swap it. Also, I noticed that when I don't have a backpack items in "active" slots actually can be swaped. None of my friends have this problem.
You can manually set button keys within the game's Controls>Soldier Buttons>Customs. There is one for Firestorm - Inventory.
Did you make any changes there?
