Yes, it can be said that there are still some bugs to work out, as is the case with many game, particularly when they're building new additions onto a 20 year old title. That being said, if you enjoyed Baldur's Gate, and how could you not as it remains one of the best RPGs ever made, then you will enjoy this expansion for it. The storyline is great, and there is a lot to do even in this short expansion pack.
