Yup, same thing happened to me on PC for two weeks in a row. I would get stuck on 5/6 for the weekly UG. Didn't matter how many I did after doing 5. It wouldn't budge. I waited longer than the lockout. No timer left or anything. Just stuck at 5/6. I haven't done any UG's since, because the GE kicked in. Been grinding for caches for the last couple of exotics I'm missing.
What's also been happening to me a lot recently is getting missions where I would need to activate and defend a generator or talk to a cut off/captured JTF agent. I would clear the room and get to the point where I need to activate the generator, but I can't. I walk right up to it, and walk all around it. The trigger to interact with it never comes up. I see the orange exclamation mark on it though. Doesn't matter where I stand.
Same with the rescue missions. I would clear the room and unlock the JTF agent from which ever closet he's locked in, and the next step would say "Speak to JTF guy" (or what ever the exact wording is), and he would have the orange exclamation on his body, but regardless of where I stand, it won't let me interact with him.
That hasn't started happening until 1.8.1. Before that, I had never experienced it before.
