Yeh good job on making a proper bug report. I think riot knows about this one though cos one of their staff used this as an example.
"Example:
Title: [Platform] Upon login, the players show up as level 0 in my friends list.
Priority: Minor
Label: Platform, Chat
Description: Whenever a user appears to log into the air client, they show up with a yellow busy circle and they look like they are level 0. This appears to happen to all players on my friends list and it seems to go away after a game, but I am not sure.
Repro steps:
1. I see someone on my friends list log into the game.
2. I notice their status on my friends list.
3. I expected to see their normal stats, but I saw them as level 0 instead.
4. This occurs 100% of the time I see someone log in."
Same with minor differences really.
