https://pastebin.com/g9TABaTN This is the pastebin for errors and information of my server. I believe this is because of a plugin or something, since my server's ram and cpu should be fine. My server crashes when the player 'JackXXOO' and 'Napking0fVembz' leave my server, I have no idea why this happens. I tried deleting their playerdata already, didn't work. Please help.
