Not sure how I didn't notice this before, but when I was swapping out the strings tonight I came across this.

There is quite a bend in the mod and pretty sure it's cracked on the back side. That and now I'm pretty sure this is the root of the serving wear I was seeing on the other strings. No idea how this happened to be honest ...

What and how do I go about getting the mods replaced?
