@nina_kali_nina @ai6yr from Royal Road auth I read:

I was about to have a real bad day today when I went to edit and upload and couldn't find my most recent working file. Despite it saying it was syncing and saved last night, it was just gone. That would have been about a week and a half of work evaporated. Luckily, I was able to recover it and it came down to a problem with Microsoft account syncing shenanigans across devices (I write on my ipad and edit/post on my PC).
