unfortunately, they all do it. I don't think I've seen a game ever that came out that didn't have "bugs", some to the point to where you couldn't even play the game. Unfortunately ~all~ the software companies, including "modern" OS writers are the same, seemingly using the users as beta testers, or guinea pigs... reminds me of when I was in a band, and you'd record, and one of the guys that had made a mistake in their part would say "they'll fix it in the mix"... back then, the easiest way to "fix it in the mix" was to erase the part and do it again... Silent Hunter 4 is a rare beast in that they eventually got close, so long as you remember it has limitations.
