If you have non-geometric layers and want to use the custom layer order, it is disabled every time your re-open the project.
This message appears in the log:

The problem comes from the fact that sometimes drawingOrder="-1" in the legend node for the non-geometric layers.
And then, in QgsLegend::verifyDrawingOrder, if a legend layer has drawingOrder < 0, it will reorder the layers according to the legend.

There is no crash or data corruption, so I'm lowering the priority.
