Hi picturedrift,
Thanks a lot for the image, that made it clear.
Yes, I can see that the initial dropping is quite different. I placed the “Influence” animation on it (Belts), so that wasn’t obvious anymore to me. The only other difference I was able to find was the frame rate, but that should not be of any concerns.
Here is the rendering in comparison that I did with Donovan’s v02 file.
I have placed the two preview renderings side by side and then on top of each other. This was the difference I wrote about above.

This was the difference I have found. I think in the overlay, that was pretty clear, but not really significant.
The initial hanging/stretching R16/R18 is quite different, and I have no indication that any parameter is different.
To just change something seems the most simple suggestion at the moment, which means for example, to change the information available on the belt. I have painted some vertex maps. (In add mode with 5% strength. so each stroke adds a little bit, to keep it not too obvious, like a round gradient).

I took the Influence animation out for this file, so we have a clear view to the problem…
You certainly noticed that I have some parameters changed, Flexion and Rubber, you might dial it down to your liking.
The problem that we see between the two versions is perhaps related to changes of the applications code. Simulations are complex, and to improve the solving time, the developer team has always new ideas, otherwise we would stuck with a slow app. With those simulations, where one decision influences the next (e.g., polygons) in space and time, the outcome might vary naturally a little bit.
I hope that works for you.
