First of all Thank you for your respond.
To answer your question...I receive the damaged safedata notification when I try to load my world with 815 days. After few seconds of loading the game breaks up loading and tells me that. My second world with 58 days is actually loading and I can play so there is espacially a problem with the ,,bigger world´´. I only have problems with the 800+ days world. As I mentioned I made a rollback right in the moment where psn had server issues maybe that is somehow the cause, because aufter the rollback I immediately tried to reload but than I received this note.
I uploaded a new file maybe you can find the issue and could tell. So sadly it seems that I lost my world where I spend nearly a year but yeah.. it happens. :/ If you find something interesting towards my data let me know, maybe I can avoid that something like that happens in future.
Thank you very much, you are doing a great job, such an awesome game.
