instead of replying in a group here.

LOL! Yeah, you won't receive much feedback there... look at when the last post was made in that group and there are no responses.

Like I said, Chaos Group does seem to be aware of some bugs that cause geometry in the model to be manipulated during the render and are working on some fixes. I think the most helpful thing would be to send a file that exhibits this behavior directly to support. You're more likely to get a helpful response if they have something specific they can work with, and it will help them troubleshoot the problem.

Best,
