Ok what just happened with the client?!

Entered a ranked game, locked in, everyone locks in, timer hits 0 and expecting to enter the loading screen. The loading screen never shows up so i force closed league only for it to automatically reopen with a black screen and sound effects of my character (talon) being picked plays and nothing more. Force restart my PC and open league again, somehow it's patching, asking for my agreement for the terms and conditions and forgot my username? Logged in (after a bit of delay due to login queue) and the game isn't in my match history + i didn't loose any lp
