[CLIENT] Bug in Queue for ARAM

This is the first time it's happened. I was in queue with a friend for an Aram game, and we were probably a minute in when we suddenly went to a loading screen for a game. The client didn't ask us to accept a match nor did we go to champion select. We got a random champion like a regular Aram, but I also had random masteries (not my previous page) chosen (my spells stayed the same though). We played the game out, and after finishing we skipped honoring teammates and the stats page and went back into our old queue. The queue timer was from the same time we were queuing up because it was the time elapsed from starting the queue and playing the game. However, we couldn't leave the party or exit the queue, and I stayed for a minute or two to see if we would enter another game, but it didn't happen (I didn't try clicking anything else, sorry). I just ended up closing the client, but I haven't gone back in to see if I could replicate it.
