Blender import single mesh

Every time I make a file containing a single mesh with Blender and import it into Unity, it will give me that mesh, with no parent. This is very annoying because it causes massive bugs in Unity.
If I export to OBJ or another format however, it will give me a parent that contains the mesh, thus preventing the bug from happening.

How do you import Blender files? Are you using the automatic importer?

Yes.

What bugs specifically? I know when I’m working with Blender files, I almost always parent the Blender file to an empty GameObject, and then add scripts and components to that object. Would that fix it?
