Around kabuki, it's sur but i don't know whereIf only there was an option to reset a quest that's bugged...
I realised that my Blake quest didn't complete only dozens of hours after I completed it and his body was taken away in the trunk of the car.
Some reported that they found him floating inside a road somewhere in the city and completed the quest when they shot him on the spot. I never stumbled upon him though...
Maybe drive around and look for green spot (fixer's car).
