Our feature-linked annotation seems to have lost some of its feature linkage ability. We have point data in a file geodatabase and used the 'convert labels to annotation' tool to make a feature-linked annotation layer (saved in the database). This is a 'living' data file and my colleague adds new features once in a while. We tested that adding new point features made new annotation and that editing the label field also updated the annotation text. Everything was good. Today that link has mysteriously broken--new features don't make new anno, and updating the point's label attribute doesn't update the anno. The annotation layer still shows the relationship class so I don't know what could be wrong. Moving points does move the anno so it's retaining the offset info. Deleting points also deletes anno but creating points doesn't create anno.
For a couple days I've been moving the annotation to be visually pleasing (1/3 done of about 2000 anno's) but nothing major--just scooting, rotating, and adding leaders. Did I break it and how can I restore the linkage?

Edit to add related info--I have a test anno layer that is nearly identical but without the annotation classes. It's the layer I played around with before starting the real one. (This is my first project with annotation, so I fiddled with settings using the test layer.) The test layer has retained its linkage and updates everything correctly--but only upon exiting the edit session. I think the only difference between the test anno layer and the real anno layer is that the real one has annotation classes and those are styled with my own settings.
