I have a field in a content type, content_type_A, whose field type is Node reference.
It references another content type, content_type_B, which has a field which i cannot edit of type Node module element. It has f.e. 10 discrete - unique values. What i need to do, is delete some values of content_type_B, and then there will remain 7 discrete - unique values. I can do this in the db, since each value i need to delete is a node in a specific table. I noticed that then the value in all the nodes of content_type_A, which had the deleted values now they have in the field under question the value NONE, which is also the default value when one does not set one. Am i safe with this? Or should I check also further in the db for more alterations
