please find my world at the link (too heavy to attache the file here)
https://www.dropbox.com/s/o0t48p1h5wijlq3/Archivio.zip?dl=0
as a side note I was able to have it work (saving at least once) copying the file directly within the game (in the world options before launching the world).
this workaround works if every time I play I first create a copy and then launch the game, but it is obviously not a sustainable way of managing the world
the file is taken from a PS4
