[Client] Cannot Join Lobby or Group After a Match

After finishing a match, i cannot join a lobby or group even if i "accept" the invite.

The issue is temporarily fixed after i log off and then back on to LoL. I am Lv 30 and unlocked half the champs, so it is not that i dont meet a level requirement for Team Builder or that i do not own the champion requirement for Draft.

Additionally, it does not matter what game mode it is or who invited me, or if i literally played several games with them. The bug happens, pretty much after virtually every match. The only time it does not happen, is if i invite.

Once again, It does not mater if it was an invitation to Team Builder (i am lv 30 so i am not restricted), Draft Normal (i have like half the champs unlocked), Custom, or Ranked. It also does not matter if it is on Twisted Treeline (3v3), Dominion, Howling Abyss (ARAM), or Summoner's Rift, i cannot join the lobby even after accepting an invitation.

I am happy the chat works fine now after people quit the queue or if someone leaves a lobby, but now it seems another minor issue (yet somewhat annoying issue) has taken its place ^_^.
