Found a New Problem in Matchmaking

When searching for a match, before you go to the map/gametype voting screen, the players in the match appear in the roster and you can click on their Player Details and all. The problem is, if you keep the roster menu pulled up as the player search ends and the map voting begins, the game does not allow you to vote for a map/gametype, even if you exit the roster menu. When you exit the roster menu in this situation, you can’t even bring the roster menu back up and the only thing you can see on the screen are the voting options, you can’t even see what everyone is voting for until the game starts loading the map

Anyone else having this problem too?

That happened to my friend yesterday.
