**Short description of error**
see subject
**Exact steps for others to reproduce the error**
# Open the attached file. There's nothing to do but looking at the viewport and reading the following description of the scene:
# The cube on the left belongs to group "Group.001".
# In the middle, there are three spheres and an instance of Group.001. These four objects belong to group Group.002.
# On the right, there is a plane with a particle system emitting group "Group.002". Problem: The cube is missing even though it belongs to emitted Group.002. I'm only guessing that this is because it's a group instance itself.
