So far, characters who've been hit seems to be nearly everyone i played that I actually took into missions, so the latest one and also worst offender:
Dyson Sphere Voth Battlezone(Not the Undine one)
All but the third aft weapon got stuck, flying a Legendary Command Dreadnaught Cruiser T-X.
Reslotting weapons let me get one volley after then they got stuck again, reloading the map worked, but even then the last aft weapon got stuck.
Vivninaa (Second worst offender, same global, first day of patch I think)
Mission: Delta Flight
All but first Fore weapon and also one aft weapon(and experimental) were disabled at the end of the mission vs the Iconian Dreadnaught.
Most other times at LEAST 1-2 weapons were getting disabled every so often.
