This has happened multiple times to everyone I know, that we go into our profile to see what champions we have and the page has completely bugged and only shows a handful of the champions. It makes it difficult to look at champions when you are trying to come up with a strategy as a team. The only way I have been able to reset it is to restart the entire client, even going into a game and coming out doesn't reset the bug. I have tried to post a picture but it keeps getting timed out. It's happened for a long time, and I have said something about it before.

Bumped.
This is still a problem 4 months later.

The champion page bugs out more often than it works correctly for me.

Every time I go to the champion page I'm just praying that I can actually see all the champions I have.

BUMP BUMP BUMP, whats the deal riot????
