I am having an issue with progressing with the quest after killing the guards. Once I kill all 4 of the guards, it still says to kill the guards. I have reloaded the saves, I have closed the game down fully a bunch of times, I have tried to repair it on steam, turned off all my mods, everything I can think of and I still will go to kill them and then that is it. It does not continue to have me search the truck.
