Startup glitch
Whenever I first start a game, I am unable to unlock or lock my camera by pressing y or spacebar. Additionally, I have to left click everything 3-5 times in rapid succession in order to do things such as shop, ping, move my camera, etc. This glitch used to occur rarely, but since patch 5.18 it happens whenever I start my first game after opening LoL. Sometimes it even happens twice in a row.
