No Reconnect Button / No loading Screen

Was just going to enter the last promo game for Plat 3, right after already having played one of the games in my promo's just fine. And after champion select screen, the loading screen just never came. So I restarted the client BUT THERE WASN'T EVEN A RECONNECT BUTTON. It just showed "Game still in process". Restarted client few more times but same thing, it never appeared. Restarted the computer aswell, but by the time I got back in, a Remake had been made and I had lost my promo's.

Found this from a year back: https://gyazo.com/7b557aceaa00892df25112c596e7c360

Yet live support tells me he can't do anything, please tell me there is something to be done about this.

Thanks
