3.b3b3 Warning after simulation

[oliof]

Good morning,
just ran a file simulation, as I am wont to do every now and then.

As the simulation commenced, I got a warning I've never seen before:

4/25/2021, 9:35:33 AM 	M37 P"0:/gcodes/blade-vase.gcode"
Simulating print of file 0:/gcodes/blade-vase.gcode
4/25/2021, 9:39:53 AM 	File 0:/gcodes/blade-vase.gcode will print in 1h 41m plus heating time
4/25/2021, 9:39:53 AM 	Warning: Cannot set print file finished because there is no file ID

The file is sliced with superslicer (slic3r/PrusaSlicer fork), and was uploaded via the built-in upload function. Same issue with PrusaSlicer 2.3.1. Uploading via DWC yields the same error

M122:

@oliof thanks. I'll ask @chrishamm to look at this.

@oliof Thanks for the report, I've got a fix ready for this. It was caused by M0/M1 at the end of your print file.
