MPC - Take over
When a node or a cluster of nodes not connected to a main terminal they became orphaned. In this state they keep their owner and last set status, but agents can't change the orphaned node's online status. In this state the nodes can be connected to any valid network - that has a main terminal - and by this the whole cluster is taken over. You can only see orphaned nodes on an island if you have at least one main terminal set up on the same island.
