How do you delete a simulation that doesn't show up in the feature manager? There are no errors in the assembly however when I open a the drawing of the assembly there appears a red cherry on the drawing view in the feature manager. When I RMB on the view and pick "What's Wrong" it says: "Simulation: This feature had an error in the last update. Edit definition on the feature to correct the problem." Any Ideas how to delete something that isn't there?
