This seems to happen on pbe only, but whenever I finish a game, the client bugs out and shows me this "invisible" message and doesn't do anything. The post match screen does not appear and I have to close and re-open the client again to fix.
Post your PBE bug reports here: something not functioning as intended? Store is broken? A champion's ability is not working? etc
