Sometimes, Papillions will get Phenex wings when viewed from the back, and vice versa with Phenexes getting Papillion wings (The picture I'm showing is a Phenex, viewed from the back)

Additionally, I've gotten a random Felidae tail before. It vanishes after you change the icon.

It's quite funny, but I have no idea how to replicate it. Sometimes it happens when you rapidly change the colors of the racial wings...but it's not lagging or anything, it just does it randomly.

Sounds like a cache error.

This has happened to many people, but I will try deleting my cache to see what happens.

Mass updating of an icon (like changing colors) makes things much more likely to screw up, so a cache error sounds about right.
