What is a coop grief?
It's when a player in your coop or trust list breaks and steals from your island.

This is something that players report a lot, but the issue is mods can't ban for it, but may refund if you're lucky.

This is because YOU as the player gave them permissions to do this, and if you gave them the power to do it, it's on you. If you ever have this happen, just know that you trusted the player, and it isn't our fault that they had been wrongfully trusted.

How to prevent it?
Trust players YOU trust and they won't steal. Don't trust or coop random people.


I hope this helps cut down on the problem a bit. It happens a ton so just don't coop or trust people you don't know, or don't trust. It's going to save you a lot of issues most likely.
