The actual reason for us not posting this sort of things more openly is usually that we receive the news so late, that it gives us time to remove the game from sales "effective yesterday" :-( It's not fair to anyone, agreed, but sometimes things like this get overlooked by Publishers.
I'm really sorry about this, as GOG.com as well as personally, as this is one of my favorite classics around here and I had some plans for making a Twitch series out of it. That would've been fun!
Now, we can only hope we'll manage to get it back promptly. As far as I know this isn't some terrible legal mess as in some cases, so things aren't that bad.
I simply ask myself what is going on at those publishers offices:
Last day they look up in there calendar and scream "Oh my god, we´ll loose distribution rights! We´ll loose distribution rights!"?! I´m not sure I can imagine, but it has to be something that chaotic, am I wrong?
