Steps followed:
Create WarehouseWreckage
(Games → blank →
w Blueprint
desktop
quality preset maximum
Starter Content ticked).
Note: I have created this project several times already and deleted it by deleting in folder view.
As I am using v5.3.2, I use the Content Browser to create a Maps folder under Content, locate Minimal_Content in StarterContent/Maps, duplicate it, calling the new file Minimal_Content_WW and drag that to the new Content/Maps folder.
I then double click on it to ensure the editor is editing the new file.
I open the associated Level Blueprint and dock it in the editor.
I add the Beginplay and Print String nodes and amend the string values and check to run.
Result is as expected.
I add a cube (Quickly Add → Shapes → Cube). I do NOT enable physics and have disabled gravity).
I highlight the chair, table and statue in turn and enable physics and change the mass for each. Gravity is enabled for each.
I run the scenario.
EXPECTED - nothing.
WHAT HAPPENS - the statue falls from the table and the chair moves.
Why???
