Even the biggest fans of Temple of Elemental Evil (no, really, the game actually has fans) admit that the game was plagued by a bad bug problem. The situation isn't as bad in Bloodlines but it's dismaying to note that the game does have bugs and they are fairly annoying. There aren't the same endless hard crashes ToEE players encountered and the bugs generally aren't nearly as severe, but they exist and can be bothersome. Graphical glitches abound, mostly clipping issues. Occasionally, you'll get a crash when loading a new area. Perhaps the most annoying bug I've run into is save games unpredictably getting corrupted. You'll have saved your game when you left off last time and when you come back, attempting to load that save will crash the game. Fortunately, Bloodlines doesn't replace quick saves when you make them and also auto saves frequently (and doesn't replace autosaves, either, or at least not often), so you probably won't lose much progress when this bug hits you, but it's still annoying. A number of people also report a big game-stopping bug towards the end of the game that requires a bit of console hacking to fix. It's just not acceptable to ship a game with a bug like that, even if it only hits a minority of people. There's also a number of plain odd errors. For example, at one point in the game, there are locked doors you cannot enter. If you try, a guard posted next to it will say, "Sorry, you can't go in there" or something to that effect. However, if you kill that guard and then try to open the door--some invisible ghost of the guard (I think that they're called "bad level script" in the mythos) will tell you "Sorry, you can't go in there" anyways. It's that kind of unpolished quality that plagues Troika's games. In terms of bugginess, Bloodlines isn't as bad as ToEE, but it's still just not up to the standard that's expected from major releases.
