Bug!! Overlay freezes during ranked multiplayer games

Today I've been running into a problem where I start a ranked multiplayer game and all of the overlays freeze within the first couple of minutes and none of the information about the in-game players show up on the scoreboard or anything. If you click around on units and the TC, after a minute all of the information on screen freezes, none of the menus will pop up, and although the game keeps playing, I can't scroll around or anything. This has happened to me four times today and I've never had that happened. It didn't happen in a standard game versus the AI, only on multiplayer.

Does anyone have any ideas on how to fix this? The only way I could exit the game was by quitting the application, which cost me some ELO lol
