Make sure you have the autoreturn option enabled:
- Menu "World"
- Parcel Details
- Tab "Objects" - Autoreturn set to 1
Stay in that window and let their objects die this way:
- Switch to the tab "Options"
- Move the Checkbox at "build" from "Everyone" to "Group"
Now Autoreturn will take care of the issue and after 1 minute you have peace
