I thought I'd just say thanks to the dev team, because the geometry engine in v11.3 is so much more stable. I have saved so much time and effort as compared with v11.2. I don't save my model in paranoia like I used to. I haven't seen a single instance of surface corruption since upgrading.
So, thanks. There's still a lot to improve, but keep this kind of openness and development pace up and you'll take this market over.
