Players being able to unclaim other peoples land

Observed Behavior

Hello, The server I own have found a bug, so if you go above a claim and try and go through it It allows you to overwrite the claim (what they are telling me) I was wondering for days how they kepted unclaiming peoples land.

Expected Behavior

So in my experience it should be able to overwrite anyone's claims

Reproduction steps

  1. Make a claim
  2. Get a friend to build up a tower next to it and click a gold shovel to select that block and go the other side and it will overwrite the claim
    As I said thats what they have told me, so if it doesnt work, there is an exploit to unclaim areas

Using unmodified client

  • I attempted testing for the issue with the vanilla client.

I was just looking in console and they did the /unclaim, IT was my land!!! Why does that command allow others to unclaim my others land???

commented

Sounds like you have granted your players griefprevention.deleteclaims, which is an administrative node.

I was typing this out. Sounds like a permissions issue.

I haven’t given anyone access to that command as far as I know of, everything has been left default

commented

Wait, if I turn .deleteclaimnto false can they unclaim their own land?

Yes.

https://legacy.griefprevention.com/permissions details what all the permissions do.

The griefprevention.deleteclaims permission:

Allows the player to delete and resize other player’s claims
