Judging by your last sentence this seems like the wrong place for what you want. This also sounds TO ME like you disconnected/lagged out during champ select (unfortunately this has happened to me as well). As a reminder, I am not a Riot representative in any way, just giving advice. Also, if you had scrolled to the bottom of the banner on the left you and READ it you would have seen
This is the place to report bugs that you find within League of Legends. Something that occurs within the Client, patching related issues, or anything that involves gameplay (stuns not working, unintended interactions between abilities, vision issues, etc.) should be posted here! Please do NOT post about disconnects or lag. Instead redirect those problems to Help & Support.
and most likely would not have posted this anyways.
