I was testing out Nations, when all of a sudden I tried running the command /n leave as leader of the Nation. It said I couldn't do it, so I proceeded to do /na delete town. Then it says that the town does not exist. I can go over my previously claimed areas and it constantly tells me my town is there even though no commands work except /n here. I can create another town and interact like usual, but that claimed area is still there without existing through /n list or /n info.
As you can see here I ran the command /n list and then /n here right after. I thought this problem might be fixed with /na unclaim, but that command didn't exist. It would be great to have it in general if players were to claim areas you did not want them to claim.
The error occurs when I have claimed land and I do /n leave. I get this message "Error occurred while executing command: null". Then the claimed land stays there, haven't tested server restart yet.
