So, I have made a server with some friends. But no one plays there anymore, even me, though lots of things there are valuable. I came on it today to see it was griefed, even though whitelist is on. I know my friends didn't do it because I trust them and the grief happened at 1/11/2021 2:58am (my friends would've been sleeping). Any reason how my server got griefed with whitelist enabled?
