The repeater is activated by a lifecycle which has a scope of the host. This means only the host runs this trigger. A simple fix would be using property updated by the trigger which onchange → relay(all players) → checker (property name <= 1). Make sure the property is a global number
Yes but the scope of the trigger is not the problem. It is only being activated for the host because the scope being passed from the lifecycle (which starts the repeater) is the host
