D-Formers not working on scene load

57331.fury

So I spent a few hours last night setting up a complex scene and added a whole bunch of d-formers to various items, but as it was getting late, I saved the scene. When I loaded the scene today, I notice that all the deformer fields have a black area marking instead of the normal red, they don`t highlight any vertices, and the deformations that were already present are no longer there. Also the handles no longer affect the item in any way.

Am I doing something wrong are are the d-formers just bugged when loading a scene that they previously worked on?
