As title, in this specific situation Offset Loose fails with just a single line.

If I copy everything and paste it on a new file, it works… but on this file I cannot make it work, even by replacing the component and/or recreating the inputs.
I loaded with grasshopper one-by-one and it’s the same.

But the bug (not grasshopper) was already there also in SR13, I just updated today to SR14.
