System Response

There is an inconsistency, which may prevent the system from displaying
parts of the project structure. If the system discovers such an
inconsistency, it isn't able to display the project element, where this
inconsistency is located. Furthermore, the system then also isn't able
to display further elements on the same level (e.g. further tasks next
to a task in the structure tree). In addition, the system then also
isn't able to display the subelements of this project element.
