[Client] cant select or even see champs in banning phase.

Normal day on the rift its the pick and ban phase except all i see is black i cant see any champs at all. I can see the chat,spells and runes etc but i cant click on who to pick or who to ban. I understand that every game has a few bugs every once in a while but i just lost promos because of this bug and it doesn't seem very fair that all the hard work i put into ranked last night was for nothing. If there is anything you can do to help would appreciate it if not its back to climbing again. I do have screenshots of this happening also. Have a 20 min queue time now -__-.
