Maybe a test preventing moves due to some reagion tests? I mean with autolevel enabled z might change with move and could move it into a invalid region? We have several such tests - some for geometric target some inside nonlinear conversion.
You could reset autolevel matrix and activate. Would be the same as disabled from coordinates but includes the transformation. If it then works it is more likely a coordinate test triggering.

What is coordinate test triggering?
I don't understand what & where it is.
I don't think i ever see that function.
