There IS actually a problem in the action LOAD SCENE.
In some conditions, it doesn't work.
I don't know when exactly, but I have one case where it's working and one case in which it is definitely not working.
As you can see in the snapshot, I have put both of them in the same state, to test them.
LOAD LEVEL is working.
LOAD SCENE is not.
Tried with all configurations, etc.
It's a very simple scheme.
In the screenshot they are both active because why not, anyway only one works.
Second attachment shows instance where it is working.
