Hey guys, sorry for the confusion, I totally forgot to check back on this thread.
To clarify: I do NOT have the game. I tried redeeming it, and it seemed like it worked, just like Barrorab described, but I went to "My games" it wasn't there and still isn't. Sorry to not say anything here, I just figured someone else got it first. If I did get it I would thank wpegg of course, as I usually thank all the people that giveaway games on
steamgifts. Maybe I should have thanked him for giving away Sacrifice even though I did not get it, but I did not because I thought people might have thought I was "bootlicking" wpegg in hopes of getting a free game, since I rarely participate in the GOG forums.
Sorry for any confusion, and I really hope the game didn't go to waste. I don't know if it's possible, but if you suspect a bug might have occured and nobody redeemed the game it might be a good idea to talk with GOG support.
Also, I'm no bot and the "script" in my nickname actually refers to movie scripts and the like.
