Has anyone seen this weird error when trying to merge two customer records?

The merge of the entity 'XXXXXXX' was blocked for the following reasons: The entities cannot be merged. Creation of the merged entity leads to following errors: You have modified the originating subrecord, and the clone can no longer be merged. To perform a merge, the clone's originating subrecord must not change before the merge. You must create a new clone

Never tried that one, but in my experience with NS errors over the years, that sure is a fancy one 🤣
