Add this block of code somewhere (ex in GarrisonHolder, or in UnitAI) to test if one can get the prop points in the simulation
```lang=js
let cmpVisual = Engine.QueryInterface(this.entity, IID_Visual);
if (cmpVisual)
for (let prop of cmpVisual.GetPropPoints())
warn(uneval(prop));
```
You can then test that for instance the rider prop point of D1958 matches roughly the one defined in the template there. Verify that values are correct.
Test that nothing broke.
