[Client] Pressing Play Again Brings You to the Custom Game Lobby

Hello,

In Patch 5.5, whenever you press Play Again, you would be brought to the Custom Game lobby, even though it wasnt a custom game. This is occurred when i was Duoing with another summoner in a ranked game. I pressed play again and i was immediately brought to the custom game lobby. I have not tried this in other game modes.

Reproduction steps:

1. Play a game (potentially with a Duo partner in ranked).
2. Win or Lose, press Play Again!
3. You will be brought to the Custom Game lobby.

This is more of a minor annoyance than anything but still wanted to point it out.
