Development Version FreeCAD_weekly-builds-36391-2024-03-11-conda-Windows-x86_64-py310.7z Problems When Rows Deleted in Spreadsheet

[BrianAtDocumentedDesigns]

I am new to FreeCad (maybe 3 months). Many of my drawings are pretty simple and driven off spreadsheets. The last two development versions I downloaded if you delete a row from the spreadsheet the model develops all sorts of errors. I suspect the "link" between alias and spread sheet cells gets broken (get "null face in AttachEngine3D ...)
