In this case you need to bake the Surface Comb modifier or collapse the stack up to that point. 

The order of the modifiers depends on what you want to happen first. Is difficult to know without looking into your scene but here are some suggestions:

1. Ground Strands should be before Surface Comb. This is how it is in all our examples. Grounding needs to happen first in this case because many Ornatrix modifiers or operations depends on a distribution mesh(which is being set by Ground Strands).

2. Many Frizz modifiers tacked can cause flickering depending in your scene setup(If the hair is moving very far away from the center of the scene for example). If better to bake them. 

3. Hair Clustering modifier was deprecated starting on Ox V6.

4. Render Settings modifier was deprecated starting on ox V6. 

Baking modifiers is up to the user in most cases. It depends on your workflow. In this case Surace Comb must be baked to avoid flickering but not all modifiers need this treatment. You can bake everything as long as you keep a copy of the original hair object unbaked. 

Clump modifier is the replacement for Clustering.

Change Width is the replacement for Render settings modifier.

Old examples found in our documentation may still use deprecated modifiers.
