I need help to figure out what happened in my database! Yesterday i noticed that some of the contacts in my db had no email address and mailing address, and today when i took a closer look, i realised that all emails and postal addresses have been stripped off from all contacts about 20k contacts.

I have restored from backup but i have not yet found out exactly what happened. I have checked the mysql logs and didn't find anything that suggests this data was deleted.

Please for possible commands or how to to find out the cause of this mass deletion.

thank you
