WarningYou should avoid changing the number of
a deformable object’s points (for example, CVs, vertices, or lattice
points) after you create a deformer. Changing the number of points
can lead to unexpected deformation effects. Try to be sure you are
happy with the deformable object’s topology before you begin using
deformers. You might want to save a copy of the object in case you
want to do further modeling later.
