[CLIENT] Dropped from game queue

I had just finished a ranked game and queued up for another game. I chose my positions and queue'd up, and accepted the afk check. While I was waiting for everyone to accept the check, I got an invite from a person I had just played with. Not wanting him to think I just ignored him, I friended him and told him that I had already joined another game. Since I was in a lobby I figured there was no harm in clicking the accept button on the other game invite. At this point I had chosen my desired champion and was waiting for the ban phase to commence. Suddenly, I leave the champion select screen. I figured someone had left or something and I was just waiting for the next queue up. I looked at the top of my client and saw that, instead of a timer, the big PLAY button was there and my status said I was still in Champion Select. Confused, I checked to see if I could queue up another game, but it immediately kicked me back saying that I had to wait as I had left a game not too long ago.

Steps

• Get to the Champion Select screen after queueing up for a ranked game
• Have someone else invite you to a game and accept the invitation

I am hesitant to reproduce this bug as it would be messing with my ranked score if I'm able to successfully reproduce the bug. I don't like/know much about client/server interactions, so I can't say for sure, but I am guessing it has something to do with the client telling the server it accepted a game invite so it leaves its current location/status. The only problem is that its current location/status is in another queue, so doing so causes the consequences of doing so. Once it tries to enter the new queue status/location, it gets rejected for having left a queue so recently. Hopefully this is a repeatable bug by y'all, because I hate it when I'm the only one able to produce a bug.
