Not too big of an issue, but I've noticed that Achievement take a very long time to get recognized (5 hours?).
Whether it is superstition or not, but I felt like I had to reboot the game and gog for it to recognize a few times.
Lately I've been triggering all the endings and the last one for me, the Arasaka aligned ending hasn't been recognized in my achievement, and I've run through both choices at the very end so technically I've done the Arasaka ending twice. Anyone else experience similar?

Edit: Also one time I got an achievement and it said "secret achievement" was acquired for like a whole day before it turned into whatever achievement it was supposed to be.
