Chiming in to say I'm having this problem, too, and it's very upsetting to lose my inked notes. Writing in OneNote is the main reason I bought a SP3, and I just upgraded to a new SP4. I did not ever have this problem on the SP3, and I was running Office 2016 on it, as well. It happened for the first time a few days ago on the new machine, and I thought it was just a fluke and I needed to restart. But it has happened every time I've written in OneNote since then, and tonight I basically lost an entire article draft because the second half of my writing was moved up to sit on top of the first half, and all the line spacing disappeared. There is no way I can find to undo this. My work's illegible and useless now, and I'm starting over.
I have turned off the handwriting recognition and have my fingers crossed that it'll work. I wish I'd found this discussion sooner!
Thanks to all who are trying to resolve this issue. I hope it happens soon.
