Keyshot 4.3 animation bugs

[JANGO]

* Live link with Creo 2.0 at regenerate relocate some part to random position.
* Keyshot cannot handle long list of events in animation.
- change axis of rotation or motion direction of a component.
- Mirror or duplicate of event can add movement of a random component and deleting it from the duplicated event can make it pop up at random during the rendering.
- if you delete some components of the assembly they can pop up at random during animation (load only final geometry, delete is not working).
- reflection of some material does not render properly during animation (some frames lack material reflection).
* THE MOST annoying something wrong with saving the animation. If rendering time for animation is long (more than 5h) Keyshot does not create folder for saving the avi file and just delete the frames. Or create folder for frames and delete them even if activating save frame output. Video output and frame output were activated, default names for folders and names were used. By using windows search found file in rendering folder name AAA.52.avi.jpg (I never specified this name).
Once after finishing rendering only video output pop up window ask to open the folder or save the animation, I chose save but key shot never convert the frames to avi it just deleted the frames (10h of rendering).

Those are the most annoying bugs I remember that haunt Keyshot since the animation was added.
Please stop making new versions of software without fixing old bugs.
