Remaked when everyone is still in the game and playing

I spawn into a game and I walk to my blue since I'm a jungler and I got disconnected (not the bug) and I reconnected few seconds after then I clear my jungle and stuff. Then I see the remake info in the chat, so I get confused and I remake since I didn't really know what was happening and when we go to the after-game lobby It shows I have a leaver buster and I lost my precious 21 LP ;-; - if you see this riot and you need proof it's a lee sin game on 7/30/2018 played around 9:20 PM Hawaii time
