My party got a match and we accepted and the CLIENT did not load me in to champ select. 5 min ban

We accepted the match and everyone else loaded into champ select but me. Chat was still operating and I am at my friend's house so we could both see that he was in and my name showed but in my client it was all black (only in the client, except for the border and chat, friends list/notifications. The way to get this repeated: Accept a match. Load the match. Watch your screen go black. Don't get disconnected. Don't quit in fear of queue timer. Get timer anyway because blacked out client. Cry.

Thank you
