Yes, we get it. The mesh is not symmetrical, likely due to a combination of reasons.

Is there a reason to keep banging on about it though?

It does not negate the issues with Poser itself making a mesh asymmetrical over time, which it does do, and has been experienced by multiple content creators, to include myself, for a good while now. It doesn't mean that that is the only reason Scarlet's mesh is not 100% symmetrical but it does contribute to the issue. Whether it's been listed as a bug to SM I don't know. I don't even know how you would go about doing so in a provable way other than sending them multiple versions of a file demonstrating it in sequence.
