Hi, I have a strange situation: Our database has several tables with one to many relationship. We have been doing data entry with multiple users and have been commiting the backend every couple days using Tortoise SVN versioning software. Occasionally we have had errors and have had to go in and delete a record from the backend (##### type errors, i think from record lock conflicts). We noticed today that some records have orphan parent or child records, and when we look back at previous versions it seems that this has happened before, but with different records! Ie, some records that were orphaned in a previous version are now mysteriously back in a more recent version. No idea what is going on. Has anyone experienced this? Not sure if the problem is with the database or versioning software, or combo. Thanks for any help, much appreciated.
