While in a SP game: goes to board editor you can later rejoin your SP game. While in a Ranked game: goes to board editor you can't rejoin without a refresh you can start a SP game though. You can que but it will do nothing until the match is ended(off of time out). The clocks still ticks while you are gone. You can spectate-ish(will show your side but you have no control) your game by clicking it. Either case you get extra battle logs that are blank.
