Hi Erkka,
I've been meaning to reply and advise of a fatal bug I've encountered, but have just been so busy with work and life.
So, I'm on Windows 7 64bit and another computer of mine is on Windows 10 64bit. Both throw this same error. I start a new story, add a "beginning" place which the system assigns as "0". I go back to the Metadata tab and fill in the pertinent information, and upon clicking "Save" the following error window pops up:


TSQLite3Connection : UNIQUE constraint failed:
places.id.

Press OK to ingore and risk data corruption.
Press Abort to kill the program.


The program crashes regardless of choosing OK or Abort, and you must tell windows to stop the program.

Hopefully this is somehow helpful as an error report.
