The latest release of Rhino caused my Grasshopper scripts fails

Grasshopper
1

I have spent two days investigating why some large grasshopper scripts are no longer functioning as expected. Initially, I thought the input data was problematic. However, when I opened a file that used to work correctly, it no longer functions. I reverted to the previous release 8.17.25066.7001, dated 2025-03-07, and everything works again. It’s a significant problem. I don’t believe it’s an issue with my computer because I experience the same behavior on my laptop.

It’s hard to give any advice or figure out what to fix without knowing what or where the problem is. The changes that have been made were probably made to try and solve other bugs so the only way for Mcneel to be able to fix your issues is if they know where to look.
Is there a way for you to revert on one computer to the previous release and the laptop the latest release and compare inputs to figure out which component behaves differently than before?

Would you be able to put together a min GH definition showing the problem?

@ar00302 thanks for reporting. It would be very helpful if you could indicate what exactly fails, so that we can address this issue. Best is if you can share the file that fails.
Large and/or confidential files you can send use here.

@Gijs I have uploaded a working Rhino file along with the Grasshopper definition using the link above. I heve mentioned this post. Unfortunately, I cannot share these publicly. If you have any questions, feel free to email me. Please note that the sort list component does not work with null values in the latest release. Additionally, I have noticed that the first part of the code fails in the cull list component, but I am not entirely sure about that.

thanks, I’ll look into it right now.

Hi @ar00302,

This is fixed on the next 8.19 RC that will be released next Tuesday.

So is it a general problem? Or just some components?
