I did that and it kept freezing and saying 'corrupted data' but would continue to load after that, though the warning kept occurring over and over again. One of the devs suggested uploading/backing up the system file from saved data management area, deleting the system file, and then starting up the game again. However, when I try to enter my main storage world, that I've been building since I got Terraria, and has everything I own (thousands of accrued materials and items) except what I'm wearing, I get a black screen with just the mini-map (which shows my section of the world properly), then the game crashes with the PS4 CE-34878-0 error. I'm able to enter some of my worlds on my main character (I haven't had time to test some of them), though every world I enter, I'm a statue for about 10 minutes or so then it wears off and I can move. The conversion process of my characters and worlds went fine with no crashing.
I've been struggling with this the past couple hours and am giving up and going to bed for now.
