Rh8 - Critical Layer States weirdness - somehow removes geometry

The issue shown in the video. I can make geometry visible, when activating the Layer state. But I am unable to display any other geometry, UNLESS activated through Layer States.

Restart did not help. File sent via Upload.

No change after Windows restart.

I tried to Ctrl+C one polysurface from one active Layer State to another, but the geometry keeps persistently hidden. I’m baffled.

Ok, finally found the culprit.
The ‘Model On’ llghtbulb was off, apparently saved by the layer state.

Have to say, I did not even know this ‘Model On’ existed. I knew ‘Layout On’, but I didn’t know you had this on model view as well.
