Today I was conducting a bit of a clean up on my server with the admin command destroytribeplayer. I wanted to delete some players who had logged in once and never played again. The first player I put my crosshairs on and activated the command. The player was deleted. Likewise the second and third players. However, on the fourth player my crosshair must have shifted and was now focused on my own foundation. Next thing I knew my structures disappeared around me, and I was sent back to the respawn screen.
Praise the Lord for Nitrado's Map Save Backups!
