MSProject XML Interface - Project Save Failed

Have instances of interface indicating "Project Save Failed" when working with project hierarchies.  However, the changes made in both the parent and child projects are actually saving to CA PPM.


The XML files produce prior to save operation are attached, where the Parent is PR42471 and child is PR44069.  They are simple 'template/test' projects for purpose of trouble shooting - found issue originally on actual projects in use.  These at least replicate the issue.


If I break the hierarchy, I can independently open each project, edit them and save them back without error messages.


Sometimes, I get this error message - not always.


Did a full removal of the interface and reinstalled - only happens more frequently, now.


Also, sometimes get the following - basically, it's lost track of the child project, where to find it's XML file:


Have attached same child project(s) to a different parent and opened/saved without error - so, starting to wonder if problem is with some of the parents (yes, CA PPM reflects real life!)
