2. Leash the copper golem by right-clicking it with the lead

3. Observe

Expected results:
Lead moves with copper golem head.

Observed results:
Lead does not moves with copper golem head.

Fix:
this can be fixed by adding this line to head bones on the "geometry.copper_golem" model in copper_golem.geo.json files:

"locators": {
    "lead": [0, 22, 0]
}

and this line to body bones on the "geometry.copper_golem" model in copper_golem.geo.json files:

"locators": {
    "lead_hold": [0, 34, 0]
}
