selecting a scene (2nd time the same or different one) after 'make run' doesn't work properly

This is on MacOS.

Very briefly I see the scene but after that the window turns black again.

Selecting something else then Materials.scn and then Materials.scn again does work. So maybe the Materials are not deleted probably or something like that?

I think this is to do with how I am clearing the previous scene - the end result is that there are no entities left after you reload a scene. Advice/help on this topic would be great!

Is the physics engine reset as well?
