Do not leave your mobile Tractor Units alone in a system. MTUs found with the owner not in system will be killed. This is because they currently loot ANYONE's wrecks and not just cans and wrecks belonging to their owners. This is, intentional or unintentional, a form of loot stealing. If you find an unattended MTU do try to contact the owner first before killing it and IF that person is in local please do not kill them.
