Can you think of anything that is different about this last week? A different machine, fresh upload of the GEDCOM file, anything related to youe work-flow?
It might never be possible to find the cause, but the fix will probably be to do the following:
- If you have a backup of the GEDCOM from before these entries put it somewhere safe [not the kiwitrees/data/ folder]
- Then run “Export” to create a new GEDCOM file with all those latest changes included.
- Now IMPORT that new GEDCOM file.
If that doesn’t fix everything, you will need to import your backup GEDCOM (step 1) and re-enter those changes.
