I've been asked to clarify
my third post in this thread, wherein I listed a million bugs and basically made Divine Divinity on GOG sound like a trainwreck.
Well, it's not a trainwreck. It is currently, as the officials have said, the exact same version as that sold at any other digital vendor like the Larian site or Steam.
But it is NOT the same version as the patched original disk version of the game. A big grab-bag of changes and fixes were LOST, and remain lost in all digital versions.
What's important to remember about that list of lost fixes is that all those bugs won't necessarily happen to you. Losing those fixes doesn't mean that you WILL get those bugs, but just that you CAN get them. As Raze once said, he played a big part of the original game without any fixes at all and didn't get any bugs.
So the problems are rare, but they're still lurking in there, and people DO still sometimes post with problems that were considered long-fixed in the patched disk versions. There are workarounds, (thank goodness for helpful players), but you shouldn't have to bust out the hex-editor or send your savegame to someone to fix it because an important quest NPC went hostile for no reason.
I'm going to edit my post in question, because at least one problem WAS fixed (the music problem), and GOG is up to date with every other digital vendor. I'm also going to remove the gigantic list and just note the patches from which there are missing fixes.
