DN reverted back to last project saved

Hi

I was working on a new project yesterday with both DT and DN (audio through, and midi from DT), and when i turned both devices back on my DN had reverted back to the last project i saved (didn’t ‘hard’ save this one yet, since i tend to only do that at the end of projects), while the DT project was still there. Anyone knows what happened here? Have never had this happen before.

kind regards

Vincent
