Error in Queue [Client]

I opened up League like I do often on weekends. Today, since I've been having a lot of problems (mostly network) I am playing in the low priority queue (which isn't really a queue, but twenty minutes of making coffee or doing work X3) Upon being inserted into the actual queue I am looking at summoner profiles to pass the time, my profile shows up blank with champion masteries and game scores. My horrible horrible chat history is there, however, as is the case with the other profiles I viewed. I get a popup saying there was an error, I assumed it was because the page wasn't loading. I check my ping, it's in the mid 30s. It's better than amazing, and my connection is strong. I get the chance to join a game, and I do; except I don't. "You have been removed from the matchmaking queue for refusing to respond to a match." It registered I pressed join, and yet it thought I didn't. I got another error, and was sent back to the home page of the League Client.

   _ I have no idea how to replicate this issue. _

    This is the first time it has happened and while I should wait for it to happen more and should have taken a screenshot, I missed the chance to remove one of my many LeaverBusters, and ultimately, have to wait an extra twenty minutes on top the the 100 I already have in waiting time, totalling up to two hours of not doing anything.

 Personally I think it should send you a warning saying "If you leave one more match you will be set in Low Priority queue" (Last game I didn't actually l didn't actually get disconnected but the client seems to think I have. The problem is that no one can change my LeaverBusters and I accept that. I don't appreciate getting them when I didn't do anything.)
