Skins do not reload after switching resource packs

What I expected to happen was...:
When I switched resource packs, my skin would stay loaded just as it always has

What actually happened was...:
My skin turned into another skin without me changing it. It looked like it does in the attatchment

Steps to Reproduce:
1. Open Minecraft and sign into your premium account
2. ...Change your current resource pack
3. ...Your skin should change to the one attatched
