I do hope you shut off leavebuster for your emergency maintenance

I received a Leaverbuster due to the game I was attempting to load into as well.. Hopefully something is done.

Generally speaking when an issue on Riot's end is preventing players from connecting, not only is Loss Prevented enabled but they go back after and disable any leaverbuster flags, penalties, or marks that you may have gotten during the issue.

That doesn't mean you shouldn't try to reconnect if able of course.

they cant disable leaver buster on a player-by-player basis, but for situations like this people are absolved from it once they push "the button"

so you'll be fine, dont worry.

I just checked my match history. It never says it happened.
