Hi Rob,
Thank you very much for the file, and using Dropbox.
I have occasionally seen this when things get CMD dragged copied. I prefer to copy and paste, but I also use the shortcut route; it should work both ways these days.
When I copy the whole Object manager into a new file and set the scene accordingly (I missed only the fps; yours is 25, and mine is by default 24), the problem persists. If I replace the Cloner and set up the Cloth newly, things work here. Example:
CV4_2025_drs_24_MGfp_01.c4d
Please load this file into a new scene and check if that works similarly. Here, it shows up fluent.
I created three External abc files, via External and Cache Scene.
I loaded all three "abc" files into a new scene and exported them into a new single "abc" file. The one that is shared here.

Is one or the other working for you?
Enjoy your project and your weekend!
