relational field not showing on custom ACS object

Hi all,

I've created an custom object type which has a relational field to a Place.

Cloud.Objects.create({
    classname : "orders",
    acl_id : acl.id,
    fields : {
        orderArray : order,
        "[ACS_Place]placeID" : placeID
    }
}...

Querying the object doesn't return or include the place data, which would be expected

Cloud.Objects.query({
    classname : "orders",
    where : {
        user_id : userID
}

Expected behaviour. The order object would include place object

However, all I can access is the value of placeID itself, no further properties
