Hi we are from Argentine and i meet a guy from German, that we buy a package from Unreal Marketplace made by him. We need to merge other package into it. But the package that i need to merge, he dont has in his vault so he cannot tell us how to fix the issues, can i make a project with all package and share with him, so he can work direct in my project and then return me with all bug fix, that is legal?
Regards

It is legal:

I don’t fully understand - can you explain more?
