I have an SSD for my OS (Ubuntu 16.04) and an SATA for software, files, basically everything else, a pretty common setup these days. I've installed the game on my secondary drive, and it runs fine, but when I try to apply patches or DLC to the DD folder on that drive, I get a message telling me that there's no game there to patch/install to.

I've tested installing it on my SSD, and when I do the DLC and patches apply fine. I do not want the game installed on my SSD though. Basically, I'm wondering why the patches/DLC don't work when I try to install them to a folder in my secondary drive, and if there is a way to make them work.

Any help is appreciated, thanks.
