Broken: version: 2.83.1, branch: master, commit date: 2020-06-25 09:47, hash: rB8289fc688b3e
Worked: (newest version of Blender that worked as expected)
Short description of error
Pressing Ctrl + G creates a new collection, but does not link it into the scene, so it does not show up on the outliner.
Also with objects selected, I would have expected the selected objects to all be placed inside the created collection,
but it does not happen.
Exact steps for others to reproduce the error
Press Ctrl + G in the 3d viewport.
If you check bpy.data.collections, you will notice that the collection was actually created
In the attached blend file I have pressed Gtrl + G a couple of times, there is a small script
in the text editor to print the names of all created collections and link them to the scene, which can be run
to see that new collections were actually created.
[Based on the default startup or an attached .blend file (as simple as possible)]
