Is it a problem to use gog galaxy? Installing the game in separate files causes the problems here and galaxy is the way to fix it, why dont you give it a try?
I put off on installing Galaxy since it was released, mostly because I had already most of my GoG games installed and a lot of mods already in place. I admit, I was too lazy to install everything again and seeing as Galaxy was optional, I decided not to use it.
Gonna have to suck it up I guess and do it
You dont have to redownload and reinstall your gog games, you just add them to your library.
Doing it later today. Thanks mate.
