after looking around at the commands that was kind of what I was afraid of, but I was hoping I missed something. Thank you for the reply. I will have to keep that in mind in the future.No, I don't think there is, sadly. Best way to prevent this is to do regular backups.
I have now tried that but I could not find a refresh sector command just the repair sector command, problem is now that they are all spread out I am not sure which sector the planet was originally in. After I deleted the plates I tried repairing all the sectors in in middle of the group but it had no effect. Though it could be that I used it wrong. An Example of what I used is /repair_sector 6 8 5 then worked my way around that start point but it only said the sector where qued for repair. Does this sound right?I believe there's a "refresh sector" command. Don't know what it is, though. Use the /destroy_entity command to kill all the plates, then restart that sector to get the planet back.
Of course, if you've BUILT on the planet and want to save that, you're kind of screwed.
