Normally there is an information panel below the map displaying information about the players in a game. Today, however, it is completely gone. What happened?
April Fools!

I've just noticed that the information panel is the only way to tell who's on your team in a team game.
That would explain why I see so much team cannibalism in the team game I'm in. Fortunately, I memorized who was on my team before I lost my information panel.
This information should still be available if you click on the Info tab from the player.
