🔒 In-game bug

I was in solo/duo ranked game for about 5 mins, then when I walked into my lane I just disconnected. So I tried to relogin the game and the system doesn't show the in-game process. It does not give me the access to the game and instead I could create a new game. But the match history showed that I was still in game. So I don't know how technically I was in two games at the same time.
