"Save" silently fails!!

[kerryland]

When I press CTRL-S Zettlr writes to the file system, but it does not always write what is in the editor's buffer. This is a massive problem!

Attached is a screen capture shows:

• I manually add "AAAA" to the start of my "00150-petrenko..." file
• I press CTRL-S, and you can see the timestamp update in file explorer, changing from 2:14 to 2:19
• I also use "File|Save", just to give you a visual indicator. As an aside I'm quite sure that "File|Save" sometimes does NOTHING at all, but CTRL-S always writes the file (although perhaps with the wrong content).
• I open the "saved" file in a text editor, but you can see that the "AAAA" text is missing from the file.

Not in the video, but I then closed Zettlr and silently lost the "AAAA" change.

I had Autosave set to "Immediately", and suspect that this is somehow related. I noticed that after a fresh reboot of Zettlr that the file was being saved almost after every keystroke, which was not the case when I made the video.
