[CLIENT] Very, Very, Very Strange and Hard to Do Bug

So, I was going to get on Vindictus for a second to see something, and because of something with it and Steam, I can't click out of it until it loads unless I want a "Not responding" error. I was in queue for a Blind Pick game on Summoner's Rift at the same time. A game popped up, it crashed, seconds before it would've loaded, and so I just sighed and went to another game. I decided to wait 45 seconds before stopping and just going to Vindictus for a second, because I'm complicated that way. I stopped it the moment I saw it pop up at 45, which was just as I got a queue "Accept / Decline Notification". I got an Error Warning saying a match queue message was displayed so I could not leave the queue at that time, or something like that, which was kind of funny. I clicked OK and looked back at the queue. It showed me as being the only person who accepted, once I clicked Accept. The notification showing this didn't leave until my friend invited me to a game.

This is a very odd and hard to actually do bug that is based mostly on coincidences. I would provide a video if I could ever get the exact second lined up again.
