Hi second-prior,
Please have a look below (link), the part about the "Pole".

I'm sure adjusting the poles a little bit might help. The little Pyramids behind the "character."
If that doesn't help, perhaps share the file, reduced to the Character setup. 9Here as C4D file or Cloud services (Adobe, Apple, Google, Dropbox, Wetransfer)
Enjoy your weekend
