EDIT : It turns out that I actually hadn't unlocked the skin yet; there was still one more stage to go. The button works fine for me now so it was probably just that. I guess this can be locked now, unless anyone else is having this problem even with the skin unlocked.

On the Skins page in the Wardrobe, clicking the "remove skin" button has absolutely no effect. It greys out for a moment indicating it's been clicked, but it doesn't actually do anything. This is highly inconvenient when I want to be able to get another zombie strain. None of the other skins I have unlocked can be clicked either. I'm using Chrome on Windows 8, and I have an adblocker installed and active. I hope this gets fixed before the end of Survival, as it would be a shame to be prevented from getting another infection because of a glitch.

EDIT: I actually can't remember if I got the notification that the skin was unlocked yet, though I've reached the biting stage. So I'll keep an eye out for the notification and update if that fixes this. Presumably I can't wear another skin while developing a strain, so that would also explain why I can't switch yet.

I can't remove mine either. I'll click the button and it will go green and say the change saved, but it won't upload. I've cleared my cache, tried two browsers, and I got the skin unlocked notification. Still can't remove my skin. I also want another one. :-(

Edit- I found a way to fix it, finally! On the wardrobe page, I followed the instructions where it said, "Click Here to reset your avatar to the default, and then click wear" and that finally worked. Maybe that will work for you, . :-)
