I use Layers for visual stacking of course, but as much for organizing objects in categories.
Therefore I routinely select multiple objects on the artboard and move them into a desired Layer by command "Send into Current Layer". (Dragging selected objects in the Layers panel is not always practical or possible.)

Condition: Layer Panel Options. Make sure "Select Highlighted" is unchecked.

Sequence (Images below.)

• 1 Create two or more Layers and put some objects on them.

• 2 Select one or more objects.

• 3 Click a target Layer in the panel to make it Current

• 4 Select Object::Arrange::Send into Current Layer

• Objects are sent to Current Layer successfully

• Repeat steps 2-4

• Objects are killed, Undo does not return killed objects.

Sometimes the objects are gone, but the Artboard graphics remain visible.
Sometimes the application must be restarted to return the Send functionality.
The sequence seems to create some kind of corruption.
