Disconnected from game -> No way to reconnect

So I'm kinda stumped about what just happened. I was playing a ranked Solo game, and suddenly got the "Attempting to reconnect" message. Nothing happened after like 20 seconds, so I ALT+F4'ed to completely disconnect, thinking I would rather do a hard-reconnect. I could refresh pages in my browser, so I had not lost internet connection. After having quit the game through ALT+F4, I was returned to the NORMAL client. Normally you are sent to the "You are in game -> Reconnect"-screen, which I was counting on, but nope. Normal hub, where I could start a new game, chat with friends, look at store etc. Closed the client completely, re-logged, but still normal client. Restarted PC, re-logged. Same. Enough time has passed now to know that the game will have finished (we were losing pretty hard), and the game is not in my match-history, I did not lose LP, and it doesn't really seem like the game ever happened. It's just gone. As I can't find the game anywhere, there's no way for me to reference the game either... Any idea what happened here? Did this happen to everyone in my game, and it just "died on the server-side", or is this a client bug not allowing me to reconnect, and not updating from the game?
