I think there was a loop that got removed or something in the past, but that piece of code remained. This was a rare enough code branch that it wasn't in-your-face always broken, and even when it was broken it was only for some of the planets in most cases. Spikey had a case where it was just incredibly in-your-face though, and it still took the better part of the day to find the issue even with such a glaring example. Glad to have that one gone, anyway.
