Bug when modifying loadout mid-match

I've ran into this issue a few times, and it's frustrating, but if you're able to wait until the end of the match and you're back in the pre-game lobby or in the next match then you're "fine". The issue comes when trying to modify the attachments on your gun(s)--I add parentheses only because I've only seen it on my primary weapon, haven't used the secondary enough yet to need to swap attachments. After unlocking any given attachment, and there is already one equipped in that slot, there is a 40/60 chance that the game will not swap the attachment to the newly unlocked one, and will stay on the one currently equipped, if you try to equip the new attachment. Mildly infuriating, and I don't know how many other people have or haven't been affected by it, but definitely in the heat of the moment it can stir up a good fuss if you've been grinding to get to that attachment and then for the duration of the match you can use it, which could quite possibly put you at a disadvantage during the game. Hope the devs see this and are able to handle it effectively! 

Otherwise great game, having a lot of fun!
