I've had 2 D strings slip off my tuner peg, got a 3rd one to finally stick, but it's kind of old... This is the first time it's been a problem on my D string, usually get at least 2 wraps, but the string that I got to finally stick on there had about 1 3/4 wraps around the tuner peg. argh. Wonder if I can get a replacement D string.
