Swain, Friends List, and Error Message

So I just played a match and I'm not sure if it was latency or not but it seemed that Swain's stun reached a bit far beyond where the visible graphic was. Another bug is in my friends list the name tab things (sure) are piling up on each other. And lastly I often get an error message whenever I accept an invite or started a custom. It doesn't do anything to effect my access to playing the game, but it does pop up constantly.

Thought I'd report these in hopes maybe some people have had this to. Sorry I don't have any pictures of the occurrences.
