Bugs are an inevitable part of game development. All programming contains mistakes; all programs, even when implemented as planned, will have unintended consequences. Sometimes they can be incredibly frustrating to deal with. Sometimes they can become a genre-revolutionizing feature of the game's core gameplay. Sometimes, they're just funny and strange, and nobody but the developers will ever be aware of their existence.Well, that's a waste, isn't it?Earlier today, Gamasutra asked its Twitter followers this question: "What's the weirdest bug you've ever encountered?"The answers are, unsurprisingly, very entertaining. We've collected below the answers that the respondents came up with. If you want to participate in our next question session, be sure to follow @Gamasutra on Twitter. If you don't use Twitter, feel free to share your own bugs in the comments of this article.
