When trying to edit content in XPM and clicking on Finish Editing, we are seeing the following error Unable to cast object of type 'Tridion.ContentManager.CommunicationManagement.PublicationTarget' to type 'Tridion.ContentManager.CommunicationManagement.TargetType'
Recently we created a new staging publication target (we already had one staging) and removed it. We are on Tridion 2013 SP1HR1
