The original version of the game had a cheat console, which meant things like impossible map generation and getting your character stuck could very easily be fixed. (The console also allowed you to respec your stats, which is not possible otherwise!) The GOG version removes the console, meaning that those bugs can brick your save. "Start a new character" is the advice on forums, which is not acceptable when there was a build-in solution deleted for the sake of achievements. The game itself is pretty fun, but I won't continue playing knowing that at any moment all my hours of progress could be lost.
