Adam Kwiatkowski The contact reference field works fine and loads a correct list of contacts for me on dmaster as well as on local. Make sure you have correct permission (access contact reference fields) set for the user. The screenshot you shared loads the profile for anonymous user which doesn't have this permission.

I've submitted a PR https://github.com/civicrm/civicrm-core/pull/8954 which restricts showing reference field for contacts not having the required permission.

i run the a cloned version from github i got this error:

User warning: The following module is missing from the file system: civicrmtheme. In order to fix this, put the module back in its original location. For more information, see the documentation page. in _drupal_trigger_error_with_delayed_logging() (line 1128 of D:\xampp\htdocs\d\includes\bootstrap.inc).

Adam Kwiatkowski This replicates for the contact reference field which is being restricted to more than one group. Modify Step 2 mentioned in the description to reproduce this.

• Add a contact reference field under custom field group selecting at least 2 groups in "Limit List to Group" field.

Updated the PR https://github.com/civicrm/civicrm-core/pull/8954 to fix the same.

Tested working fine
