Anyone else have a problem with chipped wheels? It's in a really strange place too, guess a rock must have hit it?

 

Wow, I just got my CMS and I noticed a small chip like yours a few weeks ago...a bit disappointed in the fragility of the paint job. I did not have any touch up paint for it so for a quick fix I just took out a Sharpie dotted it in. It's hardly noticeable for now.

 

By the looks of your lug nuts it was probably hit by the tire installer with the air impact wrench.
