[CLIENT] adding new rune page blocked click

Hello So i launched a draft and i didn't get a rune page matching my champso i wanted to do a new one. When i clicked on the button to add a page, the rune window closed and i could not click on anything on the client. I couldn't lock my pick but things got back to normal when the lobby closed. I didn't need to restart the client to play another game.

What i did step by step : 1- launch normal draft as support/top 2- prepick zyra 3- open rune page 4- try to add a new page 5- admire the non clickable lobby
