Defect: Arnold sequence image render not working

Description:

In 3ds max 2020, when rendering an image sequence using Arnold v 4.3.1.20, the fur/hair is not following the meshes deformations, it keeps its initial position.
This occurs with skin, morpher, skinwrap and even simple modifiers animations like bend.
However, rendering still frames from anywhere in the animation works.

Quite unusable in animated productions. I really enjoy using Ornatrix for fur and hair grooming but here I'm lost, does anyone have the same issue or have a solution to my issue? My current production is totally stuck at this point.

Steps to Reproduce:

- Create a cylinder
- Add a bend modifiier
- Animate the bend over time (ex: frame 0 initial angle state - frame 50 = Angle 90)
- Add a simple fur ball preset to the cylinder (adjust length depending on the scene scale)
- Add an Ox Arnold modifier on top
- Setup up render to use Arnold renderer, set time range 0 to 50 frame and hit render

As the sequence is rendering, we see the cylinder deforming with the bend modifier but the fur stays in the same initial position as shown in this video:
