Loading a file with a broken formula

So, I opened a file in the 20200921 Weekly Release, after playing with it in the curve segmenting experimental release, & got an error, (as well I should:) brokenformula

Node C9’s formula is Spl_C3_C6+.5

So, I was wondering, would it be possible to delete the broken node instead of fix the formula?

As you can see in the greyed out no-really-nothing-is-here view of the work when I press cancel; it does know how to not show the broken node:


Admittedly, it doesn’t seem to show any of the nodes past that point, because the top of the D pieces should have been showing.

If I ought to just cheerfully get over it, & not use main-branch copies of patterns that I like for experimental releases, I’ll be happy to do that. It just seemed like it might be a good idea for the dev-branch of seamly at least, & maybe beyond, even though it’s pretty nifty as is.

Ideally, error handling would be something like the formula defaulting to some value (perhaps zero) on error so you can at least render something. And then highlighting. But I guess if it were that easy it would have been done already :slight_smile:
