I was wondering if anyone has heard of this bug, where I go to eliminate these Hidden Dagger eliminators, who escort the Hidden Dagger executioner. I have attempted this mission three times in different variations and still the same result, after I destroy the escorts the system tells me to attack the primary target, once the primary target is eliminated it tells me to destroy the escorts, which are already dealt with. So I just sit there without any sort of mission update. Any help on this would be appreciated.
