[GAMEPLAY] After banning champs screen freezes on last champ skills and cannot choose character

Tried to play Legend of the Poro King. I was first so I was the person who was banning. After our last ban which was Akali my screen froze with Akali's picture and moves where the chat area is(I was able to get the picture to go away after clicking on the friends button). Then all of the champions disappeared and I was unable to choose anyone after which the game disbanded because I failed to pick a character.
