Small, and apparently single time bug.

I purchased some credit for hi-res skins last night.
I then joined a MP server, Cone Dodgers I believe. (Before I updated the options, so I got low-res skins).
After I got in (with all the low res skins) I found the options for the higher-resolution skins and checked the helmet and cars to the higher setting.

When I closed the options overlay, all the cars with low-res skins were fine, but (apparently) all the high-resolution cars turned to blank white.

Sorry I didn't save the Replay, the servers after that worked great.

(sorry if this has been noted, i didn't see anything on it.)
