Short description of error
Changing the Shape option of the Physics settings of a Force Field object does not refresh the animation.

Exact steps for others to reproduce the error

  1. Open file attached;
  2. Run animation from frame 1 to 255;
  3. See how each particle (inside the range) moves equally in a single direction and velocity.
  4. Stop the animation and go back to frame 1;
  5. Change the Shape option of the Force Field object from Plane to Point;
  6. Play animation;
  7. See the particles are still moving in a single direction and velocity;
  8. Stop the animation and go back to frame 1;
  9. Change any other parameters in the Force Field settings (for example disable Rotation);
  10. Play animation;
  11. Now the particles move with different velocities according to the shape.

This is not a regression, the same is seen in 2.79.

Germano Cavalcante (mano-wii) triaged this task as Confirmed, High priority.

It looks like a DEG_id_tag_update(...) is missing for the rna_FieldSettings_update(...) function, but I don't know which type to choose.

I've got zero clue what is supposed to happen, and how is the current behavior different from Blender 2.79.
