[BUG] Flash stopped working

Was playing as blitzcrank using flash and hexflash throughout a game. About 12 minutes in my flash comes off cool down but stays darkened with this green circle on it. Presing the key didn't proc flash and pinging it showed that flash was ready to use. The flash remained like this after leaving and reconnecting and throughout the rest of the game https://photos.app.goo.gl/x6Q3X4ny2xxxkpai6
