Has anyone else issues with games not starting propperly?

I had no luck finding games with the quick match finder for a minute or two. That didn’t work so I decided to start a custom match. From my perspective, no one wanted to join it so I canceled it again a while later. Apparently the game still did start - I found out about that by an E-Mail notification.

Has anyone else had a similar issue as well?

(I actually only found the mail because I was signing up on KGS in hopes of finding a match over there.)
