My friend recently tried to join the server, but half way through the tutorial, the server restarted and then when she logged back on, it put her in a flatland and didn't show that she logged on. Every time she tried to do /spawn it said that she would have access to the commands when she finished the tutorial, but she can't finish the tutorial. Thanks in advance for the help.
2 things you could do: first, when your friend is online use /staff to check for staff members and contact one of them. All staff members listed should be able to teleport your friend to a safe location. Second option is to tell your friend to use the /tutorial command. This is bound to get her unstuck, but the downside to this is that she'd restart the tutorial again. Hope this can also help.
