Playing Myself Bug

I created a game (3+) went to a tournament lobby, went back to the games lobby, when I clicked on the game proposal to cancel it, there was a game created vs myself.

I use chrome browser.

Known issue, leaving the lobby page will throw away the seek but it takes a few seconds for the server to stop sending it. (refreshing is the same as leaving)

Playing with yourself is alright
