So, this bug has happened to me before, way back in RS2 where I joined a ranked game and then during the loading screen the game went back to home page with a message saying that someone had left the game and the I had been returned to the home page.
This is where it gets interesting, I try to go back into the ranked queue but every time I click the ranked icon nothing happens so I relaunch the game and get a message saying that I had left a game and I should join back immediately, so I click join. I am then paced into an empty server in the waiting for players to join phase(which never ends) and then I leave this empty game and now I have a 5hr ban now this has just happened to me again. Good times all round really.
Anyone else experienced this?
