I believe this is an issue with the nfdc helper code not handling the returned output for "face-updated" which is not treated as a failure internally in nfdc, we had observed this prior and noted it did not seem to be causing issues. I will try and push an
update ASAP as I believe this has caused confusion multiple times and I was able to find the apparent cause. However, I am reasonably confident that you are safe to ignore it until then.<br>

<div style="direction: ltr;"> </div>
<div style="font-size: 11pt;">Hi all,<br>
<br>
I met an error when building an example to run nlsr on minindn. At last nlsr indeed converges. But there¡¯re two faces fail to register before. I¡¯ve attached the log below.<br>
