Put the summary of the bug you're having here

What I expected to happen was...:
skin to be updated

What actually happened was...:
I changed my skin to a new 1.8 snapshot skin. it worked but when I try uploading a new one, it says: Your skin has been changed! It will take a couple of seconds for it to update. but after a couple of seconds and restarting minecraft it didn't updated my skin even if I restart the launcher and the computer it still doesn;t update!

Steps to Reproduce:
1. Change your skin to a new snapshot skin and upload it go and play around with it in a world
2. upload a new one and wait and restart minecraft etc.
3. Then You should have the skin from step 1
