Conquest sector 5 boss fight bugged

In sector 5 of the Rey (Dark Side Vision) conquest the boss fight that includes the Gungans is bugged. In several battles after taking out their shield generator the Gungans seem to still be completely immune to damage and instakills. Rey's sudden whirlwind barely does any damage to a Gungan after the generator is down and SEE's instakill doesn't do anything to phase them either.

This is also even more irritating because i am at the moment pushing for the red crate since i really want to unlock this lifter for my SLKR only for the boss node to be bugged
