After updating Old World, the PYDT-mod stopped working correctly - at the end of a turn, it does not ask for saving, but starts the next player.
My friends and I are also experiencing this.
I pushed 1.0.3, it looks like old world changed the signature of the save game call, I guessed what the new parameters should be and it seems to work…
I just posted this in the Discord as well, unfortunately while this did restore the behavior of the automatic-save-and-exit after your turn, the save file is produces is rejected by the PYDT server.
Updated the old world parser, all should be good now.
