I thought the GOG version would be "somewhat" bug free, but I was wrong.
Most of the bugs on the disc version are still present in the GOG download.
The most obvious is the "missing boss" in the 1st Act, 2nd BF dungeon.
Once again, it's not there.
I have all the quests from the Act 1, BF merchants, but it does not "trigger" the 2nd BF dungeon monster. So, I will "fail" this quest since the monster isn't there.
Any help for this issue.. thanks
