Champ Select Crash, Lost 3 LP [Client Bug?]

Bug: Loaded into champ select and got to banning phase, then kicks you out of banning phase and shows only the map for about a minute then returns you back to party.

How it happened: Was duo queuing with a friend and we accepted the queue, got into the match. Banning phase starts then the lobby crashes and it shows the league map in the background but you cant do anything. Kicks you out and back to party after a few minutes. Lost 3 LP.

I want my 3LP back...
