Re: Mass Effect 2 LE Achievements Unlocking in Steam but Not in Game

Okay, hilariously, after giving up on the second try to unlock Samara's loyalty mission achievement, when I restored the save point I made that was past that (made when I noticed the problem, investigated, and then exited the game as part of my troubleshooting), now that save shows the Doppelganger achievement active and I can select the associated bonus power.

So, it looks like that DLL file is potentially somehow linked, and even if the achievement doesn't initially pop, fulfilling the criterion again might be enough to eventually activate it. (Or this is all random, and I just got lucky.) In any case, I'll just put up with the Origin toasts, since the bigger problem I used to have of the entire in-game overlay being active seems to have been fixed.

ETA: I was also able to unlock the Ghost Ship achievement in Origin and in-game. At this point, I'm going to say the deleted DLL was the problem.
