OpenMW-CS: Deleting an instance requires reload of scene window to show in editor
possibly related to #832 (closed)
deleting can be undone by ctrl-z before reloading.
steps to reproduce: delete an instance in scene window, it doesn't disappear right away, only after scene window is closed and opened back.
instance / object can still be selected so it can be argumented that not disappearing on delete is a feature but not something what is normally expected.
when openmw is launched from inside of openmw-cs the change is instant ie. doesn't require reoload so this is more like a QOL feature.
