Controller code

$model = \Abka\Business\Models\UserSellerDealings::findFirstById(823);  // record exists

var_dump($model->actionBaseSnapshotId); // show current value =12

$relatedModel = $model->actionBaseSnapshot;  // acess via magick property to related model

$model->actionBaseSnapshotId = 16;  // set new value (related record exists)
$model->migrationTime = time();         // set another property (for test)

var_dump($model->getChangedFields());       // show changed fields (actionBaseSnapshotId mark as changed)
var_dump($model->hasChanged('actionBaseSnapshotId'));   // amother test of change (result=true)

$status = $model->save();                       // saver model
var_dump($status);                                      // show status of save (true)
var_dump($model->getMessages());        // show error messages (void array)

Field actionBaseSnapshotId cannot change. The problem appears after the magick call $model->actionBaseSnapshot. Result:

string(2) "12"
array(2) {
  [0]=>
  string(20) "actionBaseSnapshotId"
  [1]=>
  string(13) "migrationTime"
}
bool(true)
bool(true)
array(0) {
}

but field actionBaseSnapshotId not changed (migrationTime is changed) and UPDATE query look like

UPDATE `user_seller_dealings` SET `migrationTime` = ? WHERE `id` = ? array (
  0 => 1529764359,
  1 => '823',
)

If i call $model->getRelated('actionBaseSnapshot') insted of $model->actionBaseSnapshot all work fine

Just don't use really those magic thing, best add method getActionBaseSnapshot where you will do getRelated('actionBaseSnapshot')

It is strange that the behavior is different. It is not right.
