System Information
Operating system: Windows-10-10.0.18362 64 Bits
Graphics card: Quadro P2000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 417.71

Blender Version
Broken: version: 2.81 (sub 10), branch: master, commit date: 2019-09-10 22:12, hash: 4ce3fbd52a
Worked: (optional)

Short description of error
I can't seem to get Verts- or Faces-Instanced metaballs to render, but they show up nicely in the viewport. This behaviour can be observed with Eevee and Cycles.

Exact steps for others to reproduce the error
In a fresh standard Blender scene create a metaball mesh, parent that to the standard cube and activate Verts or Faces Instancing in the context menu of the cube. Now render and (I) get a blank screen.

This is because the original instance is motherball, and by design an original instance is never rendered.

See instanced-verts-as-an-arranging-tool :

The original monkey head at the center and the parent mesh are still shown in the 3D View but neither will be rendered.

This issue has been reported multiple times.
So I will set it as a high priority.
