I'm rather devastated that by installing the latest patch my save game directory is completely empty. That means that I've lost my game, and all the hours I put into it. This is distinctly not how Dee explained that this process would work when I asked him about going from the beta back to the full game.
Oh my word, so many hours lost.
Seriously guys, backup your save directory before installing this nuclear patch!!!
EDIT - It was determined that this occurred because I was using hard links to my save directory in order to use Shadowkeeper. Apparently the installer actually deletes the source directory rather than just the link to it.
