Modifying placed families causes 'serious error'

I'm writing an application which reads text XYZ coordinates and generates a Revit model.
The application works perfectly; levels, floors, walls, doors, rooms, etc. are created/placed.
However, when I try to move something (a door, a wall) I get "a serious error has ocurred..."
When I undo up to the door placement transaction (meaning that now I only have levels and walls) I can now easily modify the walls that were automatically placed.
It seems that there is something about the door placement that I perceive as being 'over-constrained', which does not allow modification.
Am I on the right track? What should be my next steps to ensure that once doors are automatically placed, they can be easily modified by the user?
The following is a snippet of the door placement transaction, in case it helps.
t.SetName("Place Doors"); t.Start();
for (int i = 0; i < m_Walls.Count; i++)
{
//Note that each DoorPts object holds extra information, not just XYZ points. (See DoorPts class)
doorGeo.DoorPlacementPts(application, m_Walls[i], i);
foreach (DoorPts thesePts in doorGeo.DoorXYZ)
{
if (thesePts.wallHost == i && thesePts.isHosted == true)
{
FamilyInstance instance = doc.Create.NewFamilyInstance(thesePts.Pt_Place, SelectedOptions.SelectedDoor, m_Walls[i], thesePts.Arc_Level, StructuralType.NonStructural);
if (thesePts.isflippedFacing == true) instance.flipFacing();
if (thesePts.isflippedHand == true) instance.flipHand();
}
else continue;
}
}
t.Commit();
