Minecon Cape

I decided that I should finally get the newest version of the Minecraft browser and only thought that my game would be a bit faster. I opened it up and started 1.13.2. I was messing around with everything and I noticed when I accidently pressed F5, that I didn't have a cape. The cape button said it was activated so I have absolutley no idea where my Minecon 2017 cape went.
