Soo-Won doesn't take Defiance Bar Damage

[Shiv Deeviant.8072]

Ran a Dragon's End Meta today before reset and had an issue where Soo-Won's Break bar would appear and no amount of CC would break the bar after 60% was reached. So we got ONE break in, then after that no further Defiance would break. Still managed a success, but it was certainly stressful. Another player in my squad mentioned that it had been bugged in the same manner yesterday.
