[CLIENT] Random champ select freezes/disbands

On opening league, occasionally when a new lobby is opened for the first time it reverts back to the league news front page of the client. Frequently after this, and usually randomly on it's own, the champion select client counts down to 0 on someone's selection of ban or champion, and then the client claims that the game has disbanded the group with a link to the bug referral page. This either then enters the game without me being present in the lobby, resulting in no champion swapping or mastery checking ect, but the only available way for me to check if i am in a game is to log off and log back on to find a reconnect screen, as after the disband you are returned to the league news screen again. This has resulted in numerous leaves and losses from this now in ranked, as it only appears to occur in the ranked champion selection lobby?

My most frequent way of causing this:

1: Restart a client session 2: Join a friends lobby, without checking for the lobby crash first when opening league ( or if a game has already occurred at this point just join the friend you previously played with as a play again lobby) 3: leave the lobby page, I have avoided the crafting page now just in case it was this 4: wait in champion selection, at some point the count down timer will freeze at 0 on a champion but allow selection of everything else, except no typing into chat rooms unless it is a private chat 5: wait for the disbanded pop up box in the old banner style with white plain text, like the old pop up problem boxes before the client revamp, this is then replaced with the new clients bug splat go to forum for help text box 6: If you had a champion selected, quit league and re-open, if the game has decided you are still present in the champion select lobby because you had a champion locked in then you can reconnect to the game with all previous games assets (runes masteries summs) all held the same. 7: Get flamed for troll lol

Currently waiting out a leave again because of this, I am going to attempt a full program refresh again to see if repatching it will solve anything, I don't believe it is my internet currently because all other programs have been running smoothly using the router connection whilst this occurs, but i will test with other connections and come back to add further comments. These problems seem to have only started occuring due to the last patch and have never happened before this though which seems incredibly odd? I will return with any solutions if i can find any to try and hold this off.

EDIT:

new method to make this occur:

1: enter que 2: look at another persons profile via right clicking in the friend box to go to their page 3: return to the que screen and attempt to type or get any response 4: causes the post freeze results as explained above

This is the most recent way of causing this bug for me
