Something strange happened during my practice session today. It seems that the factory Hammerhead string has twisted almost one full turn out of the blue. It also looks like the serving around the idler wheel has started to fray.

Could the serving fray cause the string to twist or vise versa? Can't figure out what's happening.
I've shot the bow a bunch since I purchased it in Feb/March without issue.

Do the strings just twist or untwist suddenly, I've never experienced this before. Is it a simple fix to add twist and/or redo my peep?

Is it time for a custom string? Will? Why does this stuff have to happen a week before the season starts?

Thanks any help is appreciated,
