[CRASH] Game just vanished from existence

Just had my game give me the old "reconnecting" BS (this isn't that rare I play on wifi and my provider is bad at their job, this time though my connection was fine) however I pressed alt f4, which occasionally jogs the game into reconnecting. Instead of giving me the initial warning for afk and few second delay, the game just popped away, and instead of the option to reconnect to the game, the client showed up as though I were ready to look for a new game. I exited and relogged, same deal, like riot is HIDING the urgot jungle game I was setting up to carry in
