Bug in Champ Select

In champ select I was first pick (banning) and I was unable to ban. No champs showed up in the champ feed and I double checked I didn't have anything written in search bar and I didn't. I was unable to ban all three bans because no champions were present. Immediately after ban phase the champions showed up and I was able to pick a champ to play. I think it had to do with connection timing out right as I joined lobby but I was still able to chat, etc...
