I can't believe this crap.
I ignore the on-screen error by using the part in the bin, which doesn't error, and now I load a newly made SCH drawing that I did exactly the same way as yesterdays svg, and now none of the contacts work. It's just one solid image like it's all one path.
I load the new SCH drawing into the other IC that doesn't error, and it works fine.
For some stupid reason my old made SCH svg in the error part is fine, but my new exactly that same one isn't.
Another day wasted doing a video that errors half way through, so it all goes in the bin again.
