I don't know how many times this has been posted, if at all, but here goes. When you click champions in summoner profile, and filter it by available, it's all good. But if you go to another tab, or click Play, or visit any other page and come back, champions are missing. It's quite annoying. It seems random ones disappear. If I go to recently purchased it's also random champs. To fix it I filter it by Not Owned, then Owned, then Available and it finally fills in all the champs. Seems like an easy fix, but quite, quite annoying!
