The feature index of the feature removed or -1 if more than one or all features are removed. Note that the feature indices of all features following the removed one(s) will have changed, but their McFeatures.Identifier will not.
Remarks
This event is fired after the ChangeMade event for only those methods that explicitly remove features while leaving the McFeatures.Identifier unchanged for any remaining features. Actions that remove features as part of some other action or ones that potentially change the McFeatures.Identifier for remaining features will fire the Restructured event rather than this one.
