dirtyharry50: My statement stands. I have read the post. It is my understanding the game is broken without the mod which I imagine is why it was added to the release by GOG in the first place. Normally, they do leave modding as an optional thing but apparently in this case it was deemed necessary to provide a working game.
You did not need to require that it be removed. End of story. I will absolutely agree however that they should have obtained your permission to use it before applying it and selling the game that way. Thus in my comment above I did not leave GOG blameless in this either.
wpegg: ahatchwbciii is a really good guy, who was getting a lot of abuse on this forum for exactly the reverse of this problem. The game had certain areas of instability that were attributed to his mod. GOG were dragging their feet and not addressing this, so I am guessing that he forced their hand (or that GOG finally acted). The situation now is the best of both worlds - you get to decide.
Please do read some of the more recent threads as he suggested, you are not fully aware of the situation.
I did not need to be aware of a lot of other threads surrounding this issue to take issue with removing the patch and breaking the game. That was not a good solution to the problem. Of course, if GOG had not stolen his work without his permission this never would have happened. So ultimately the greatest responsibility for this lies with them.
At this point GOG should pay the guy to provide a patch the fixes only what is broken in the game and adds nothing else and rerelease it that way after testing it for stability. If they cannot come up with a stable game together, it ought to be pulled and this is how this should have been handled at the very start. Again, I blame GOG for most of this, not the creator of the mod.
