Upvote and bump to keep the thread alive for Riot to see.

Thank you for the support! The list keeps growing and growing

A Riot post will add more attention to the thread so would be nice to have one

Over 60 Bugs so far

For a complicated Bug
Description:
In champion select, on the dropdown menu where your mastery pages are listed. Mastery pages of another player appear as items instead of your own mastery pages, but really they will apply your own mastery page (first item = your first page and so on). Only the name of the page and description tooltip that shows will appear to be the mastery page names of another player.

Steps to reproduce:
- Visit another player's summoner profile.
- Click on the Masteries tab.
- (possibly not needed) Have a look at each page.
- Queue up for a game, and check your masteries list.

At this point you should be seeing the same pages as the player's. Clicking on an item will return it back to normal.
