Blueprint Library Function not working in standalone!

I had a set of functions defined in a Blueprint Library Function which works when PIE.
However it looks like the functions are not called when playing in standalone?
I’ve then created another Blueprint Library Function and that works.
How could the original library break?

I can tell you that the library is not getting packaged for some reason. I can’t tell you why though…

Thanks! Is there a specific place/way to check what does and doesn’t get packaged?

Unfortunately no, because it’s supposed to happen.

You can try things to force it, like putting an actor that uses the library in one of your levels.
