Hi there holger, I've seen many of your replies to people with this problem, you seem to know plenty about this.
I am new to the windows ecosystem and about 2 weeks ago I made the stupid choice of creating a new disc partition then moving my entire windows C drive "documents" folder to the newly created partition (E:\)
That has screwed with all my games. For ME3, I have tried launching it with the -nohomedir and ran both apps with admin. Initially, nohomedir worked and created a save for my newly created character/career in my D drive(where my game is installed) under Program Files (x86)\Mass Effect 3\ save folder. It was able to create save files for the game. But once I launched the game removing -nohomedir it returned back to its previous state — where I could still play and save games for my previous careers but can't create and save any new ones.
I know now I shouldn't have touched windows stuff.. it's so confusing as I have multiple "Documents".. one that I moved, one inside OneDrive, one in "User". I'm not sure if the one in "User" is even the same as the one that was in C:\ Documents.. I'm wondering which document is the real one that Mass Effect 3 is actually reading, and if there's any way to find out and fix this. I would even revert moving all my documents from Drive E back to C but I don't know if C:\ Documents is there anymore.. I think this would have fixed many problems ^
any help is appreciated, though this game is more than half a decade old. Thanks
