We have an issue that is seemingly indiscriminate, but some node content is disappearing and on display it kills the whole node and theme. The content fields on these nodes is being moved into field_deleted tables but we (the 2 developers on the site) are not doing anything that we know of to trigger it--it seems to be automatically happening. Any ideas?

A few things we know:

It isn't happening across all nodes of a certain content type, just some of them.
The fields being changed include file fields, taxonomy terms, and text fields.
We're not finding any watchdog error messages related to this.
We recently upgraded to 7.41 and it seemed to be working fine until we started noticing some nodes disappearing. We had also run into this problem under previous versions of Drupal too.

One other piece of information related to this: we had a content type that we recently converted to another content type simply by changing the content type name in the database. Since all the fields that we needed lined up correctly (because they were the same field), we figured this wouldn't be a problem to do in the database. Would a change in content type name cause Drupal to do some unexpected automatic handling of a node's fields.

There is a good chance hacking the database may have caused this. Can you restore your database to a time before you made that change on a test system and verify?

Thanks for the reply. We're also noticing some uploaded files (to nodes) have disappeared from the files directory.
