I'm just jumping in to confirm I'm also having this problem, from my other post: Not OP, but I can confirm the exact same issue. It definitely seems to trigger when changing loadouts, but I think it may just be related to changing gloves. There are a couple of times that this perk bugged out before I started messing with loadouts at all. To answer your question @UbiSailorScout it applies for flashbangs, concussion and frags when I just had the bug occur tonight. I switched between concussion/flash and concussion/frag when it happened, and it still persisted. I swapped and unswapped my gloves back to To Order, still bugged. I swapped and swapped back to my loadout, still bugged. And like OP only way I have EVER been able to fix this bug is to log out. I even died and reloaded a mission checkpoint several times hoping it would reset the talent to no avail. Hopefully this gets fixed because Mad Bomber/To Order is my absolute favorite build!
