The last few days I've encountered a problem with a ridge going behind my head in my wbbb. I don't know what changed, as I'm pretty sure my suspension angles are right, and my foot end is about a foot higher than the head end. Tension is good as far as I know, but this ridge came out of nowhere and it feels like I'm resting my skull on a rope. Does anybody know what could be causing this?

If at first you don't succeed, don't go skydiving.
