I'm at a point in the story where I'm with some 50 mercenaries disguised as French soldiers. My objective is the text in the title, and 3 targets are marked on my map as "targets". By that I mean they have a red bullseye icon on them. I'm given 20 seconds.
The problem is; the second I kill one of them, I'm desynchronized! It makes no sense! I'm told to go kill them, and I lose if I do. I'm not exactly given much time to ponder on the situation either. I'm on my sixth attempt now. Every time I fail I have to walk for like 2 minutes to get to the point I failed.
Edit. I've even tried to run ahead and poison all the targets way ahead of when I'm given the objective. They don't even have the courtesy of dying before the objective timer has run out and I'm desynchronized. THIS OBJECTIVE IS IMPOSSIBLE
And also, I've lost count of the number of times I've retried this objective now. It's over 20 times.
