It's called software and programming. With millions of lines of code in the game, some is going to be off. So if expect a game without glitches or bugs, don't play a game.
What matters is how they fix it, and they fixed it rather quickly. It may not look good, but it's nowhere near as bad as the forums are making it out to be.
Agreed, I thought Bungie found the problem quickly, they worked the problem quickly, they made quick, decisive decisions, and they fixed the problem quickly.
That being said, it is just horrible optics, doubly so when looking at them celebrating their separation with cheering and champagne glasses in hand. All of us are mature enough to recognize mistakes happen..., but this was a doozie! lol
