No auto nodetitle if field is <Hidden>

I have no idea if this was intended when Auto_Nodetitle was created or not: when using token to generate an automatic nodetitle from a custom field, the particular field must be enabled in admin/content/types/content_type/display. Otherwise the module does not work and will not assign a new title.

Here was my problem: I created a new content type (screenshots) and a node_reference field to an other content type (videogame). Using Auto_Nodetitle I wanted to use the title of the referenced videogame in the screenshots content type. The first time I created a node, the node_reference field display was set to Title (link), no problems there - the node was created just as planned. The second time I tried to create a screenshot node, the node_reference field display was set to and thus no autotitle was created, there weren't also any error messages.

The workaround for this problem is to enable the field display and hide it using the template file.
