Preview model disappears after adjustments (NOX)

[CaptainSweatpants]

Just switched over to the NOX css and love the printing screen now with the larger model preview while printing. But I just noticed when I make an “adjustment” (in this case z-babystepping) when I hit “save” and return to the printing screen the preview model is gone and just a blank area displays instead.

This bug remains after the print is done as well. It only seems to correct itself when starting a new print.

Update: so it seems pressing the small percentage circle will bring the model preview back again. So I suppose the “bug” is the model disappearing in the first place.
