I tried a bunch of different things like using your save, using my characters in your save, using yours in mine, making some very small changes to my save (like putting a new custom world in) and nothing works, I always get either the save data is corrupted when trying to copy the data to the PS3 or Terraria itself reads the entire save as "corrupted" and it forces me to replace it with new blank data.
Was worth a shot though.
