[CLIENT] Invitation Dodge

While i was in a ranked champion select i received a game invitation from someone (they happened to not be on my friends list so i was curious) the odd thing was that the invitation came through while i was in champ select. In addition it had options to accept or decline... i chose to not respond at first but then curiosity got the best of me so i went to my invitations tab and hit the checkmark to accept... It immediately said that all of my teammates left the champion select but i was still in it. I remained until the countdown timer expired for the last person that was up to pick/ban. Then it dodged me to main screen and gave me a 5 minute wait timer. So now out of curiosity to establish whether or not there was a bug... I am out some LP.
