Team Builder Bug
Whenever a team builder is created and you select your masteries but then go to look up a different players masteries (inclient) your mastery pages have their names changed to the person you looked up. So for example if your playing a new champion that you have never played before, and you go to look up a pro player for their masteries then go back to your team builder and check your masteries, all your mastery pages names will be the mastery page names of the player you looked up. This bug happens without fail every time.
The result is an error that says "A suitable error message could not be found." every time you try to select any mastery page and you have to remake the teambuilder.
Note: Sometimes when you go back and press the masteries button and they wont appear changed but as soon as you try to scroll down they will change
