Hi tonvogels,
Sorry to hear that, but beachballs are only fun close to water.
Have you explored if a Voxel size change will help? Or Caching the setup.
Besides, as another trainer (Jonas) pointed out, in the “New.c4d” use, sometimes parameters that are not the most comfortable to work with in some scenes are stored. Could that be the case?
Perhaps check with the support:

All the best
