I found a bug with the quests when importing without exiting the game.
I played the game in Easy Mode so as to get a feel where everything was, intending to lateron replay in Hard Mode after checking what I missed, so I could do it as perfectly as possible (all secret rooms, all quests). After the gripphin, my game "ended" with most of the quests still open. Instead of going back to a save, I decided I might as well switch to Hard right away. When I imported my save from Millenium I without exiting the game, I had the quest list from my first game.
(It's easily fixed, I just closed the game completely and tried again. Just thought you might want to know about this.)
In case it matters: the version I'm playing with is downloaded from bigfishgames.
