Not sure if anyone else is having this problem but I'm unable to complete any of the challenges - I'm stuck at 1/3 on the first challenge. As the title says, I can't seem to replay the entire Mission Archangel. When I reassign the mission, it begins at the part where you search Dengoso's apartment. The first half of the mission, where you investigate the truck crash and meet up with what's her face from R6 and go and investigate a Sicario camp and have a firefight...that part can't seem to be replayed...
Additionally, I'm still affected by the mission attachments bug. Magazines (some extended, some large,etc etc), underbarrels (one of the laser sights, probably a few others I'm sure) and muzzle attachments (ie. Compensator 2) are missing, most of which have already been mentioned in other threads.
It's hard to really be attached to a game that doesn't respect your progress. I understand everyone makes mistakes and fixes are sometimes more complex than they seem. However, the community is quickly losing faith in such an unreliable game and would like to hear some good news sooner rather than later.
Never mind - looks like I need to start the mission in Caimaines. Sorry for the false alarm.
The rest of my post still stands though.
