It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Where's the changelog for the BUTTERY PATCH edition of the game? GOG didn't issue a separate patch for this, instead you have to redownload the full installer, but there are no patch notes so I don't know why I should do this.
[edit] according to Reddit the new patch deletes saves, so beware. Might possibly include some spyware.

I did some digging, and it seems that saves aren't deleted but the directory for file saves has changed name. Saves can be moved into the new folder and will work well, if that happens. This will probably be fixed soon too.

I'm interested to know what else was changed with this patch though.
