that would be a big help for me too. I encountered a bug in the Gallant thief level. There are other gamers (even on console) with the same bug. There is a moment where you'll need to get past a retinal scan, but I don't receive any waypoint or objective. I see the retinal device, I found the place where we should find somebody (in the canteen), but that place is empty too. I saw on youtube what is supposed to happen, but nothing at my game. Reloading the level doesn't seem to help either. So I'm stuck in that level.
Thats not a bug, you just missed the door at the very beginning to unlock the objective, same thing happened to me. Just retrace your steps and go up the ramp and turn left, not the retinal scanner ramp, but the beginning one
So I've been trying for a while now to get my savegame to transfer over from my desktop to my laptop (and vice versa) and while the checkpoint itself appears to come over just fine, I am unable to get the unlocked missions to carry over. This ends up effecting the gunsmith items since some weapons aren't unlocked until you complete a mission.
