It seems to be related to a new feature from 5.8.6 “New : The Google Map field saves more location data in version 5.8.6!”

Works like a charm, Thanks,
We have the same issue, we create maps with pointers that need to be geolocated precisely.
Is there an option to disable this feature ?
@adammontague : Can you share your fix?
Thanks,
