[CLIENT] Teambuilder Masteries Bug

While in teambuilder, it is possible to bug out your masteries with a friend's masteries.

1. While in a teambuilder lobby, go to a friend's profile and select one of their mastery pages.
2. While looking at their mastery page, hit the home button to go back to the teambuilder lobby.
3. It will now show you as having your friend's mastery page. Hitting the drop down menu to change masteries will now show your friend's list, and selecting one will give an error message.
4. This can be fixed by going to your own profile and looking at one of your mastery pages again.

I'm not actually sure if it ends up using your friend's mastery page or not.
