Message Chat bug! fix plz

This bug have happened lot of time to me and it's annoying, i don't know how actually this bug happens but i can sure it's related with the party lobby, when my friends and me searchs for opponent, i cancels the search and back to party lobby (some rune change :p) and i sees friends icon as a cannon minion and in the chat only appears " qwertyuiop has joined the lobby" and not my other friends, and i can't chat with my friends, also when we start the party, i tries to chat with one each other separatly, the private chat cause the bug which repeat all the i thing i typed earlier , like if i typed lol earlier, i type another thing, it repeats the thing i typed and the lol*. After closing and opening client again it fixes, but it's annoying to close and open again, also when i closes the private chat and opens it again, the same happens, and with a phrase "input chat text" in the chat before i types anything. Hope Rito can fix it.
