Beta Client Knocking Me Out of Que and During Loading Screen

I really like the new client, but the son of a gun is costing me. I'm on penalty right now for que jumping when I didn't. Basically I had two instances where it fumbled the ball. The first, it declined a match when I clicked accepted. This was after struggling with a frozen mastery screen, so I figured it might have been my computer and restarted without reporting it to Riot.

The second time I made it through champ select and while on the loading screen I kept getting the error that I needed to check my internet connection. I was fully connected and able to file the bug report online with Riot.

None of these errors occurred early in the day when the servers weren't busy. Only in the evening when I am assuming there are more kids on, probably making the servers busy.

What I'm wondering is if anyone else has had this problem.
