Problems making a longbow

[Bear]

I don't know why I'm having problems with this, as far as I understand I'm doing it the way it should be done.

I'm holding a server, in a place with a string jig, trying to add silkstring to the longbow project but get the error message that it doesn't need any.

Am i doing something wrong or is this an error?

This is in the swedish environment.

You need to make a bowstring with the string.

Then add the bowstring to the project.
