Probably the most annoying bug.

Scenario Imagine queuing with your friends, and you find a game and get put into champion select. Then out of nowhere one of your friends say they crashed and the game says they have left the lobby. This did not queue dodge so your friend tries to reconnect by logging into league. Once they do so, they are at the front page of league, but there is no "reconnect" button since they did not disconnect from an game, just the lobby. So your party is forced to wait until he fails to select a champion in champ select and wait until his ban is over before being able to queue again.

Summary There is an issue where if you crash during champion select, it doesn't stop or let you reconnect until you are unable to select a champion (because you are not in champion select) and gives that player a ban. If you are a solo player, it won't allow you to start another queue until the champion select you crashed in stops. Although you do not receive a ban.

This is very annoying and when you play with 4-5 people this is sometimes a daily issue.

There should be a way to reconnect to champion select if you crashed, or players who queued with friends shouldn't receive a ban.
