I just moved my E18 save to E19. Had a lot of struggles as well. Found a new solution. I couldn't drag the file to the new Reborn folder, as it just created an alias file. Cmd drag pulled it over. Then it wasn't reading the game.rxdata file. I had tried renaming it to game.dat as well.. Probably it had the same name as the existing file or I named it game.dat or .... I used the mentioned idea above, to copy an overwritten save or duplicate of my most recent save, and then dragged it over, and it was the normal blank file and not a txt file. I had used get info on the faulty file, so the info was already open, and in the 'Name & Extension' section it showed that there was a hidden extension of .dat, so my faulty file was game.rxdata.dat. Something happened to cause that, but after deleting that, the file went back to normal and was usable.
