fix #101

Maybe it wasn't my changes that caused the failure.

Yes, I think it's an issue with the newest julia version (Julia 1 is failing). 1.6 on mac is also failing, but mac is always a pain...

I will check it out, I do not think this has to do with your changes.

Are the tests running fine on your machine?

Yes, all the tests have passed on my machine whose OS is Ubuntu 24.04.2 LTS x86_64.

Hi @SeptemberMy, could you update your fork with the new changes? I believe the error has been solved. Once the tests pass here I will merge this. Thank you again.
