Agreed hopefully it gets fixed as it was the basis for my strea. And i had alot of really large builds im proud of and wouldnt want to lose.
Unfortunatly i dont have access to a pc at the moment and its on my ps5 so no.
Also Having the same issue with a 1 year world. Had the same bug when 1.18 released
I have also been having this issue with my 5 month old live stream series world. I have a backup on a cloud save but its really disapointing not being able to update it. And explore the new stuff. I was playing it the night before around 2am on the 30th and then when i got off work to stream it loaded and had no textures or pets. Then it promptly crashed the game and i cannot load it at all now. Same issue as the attached images. My world is 956mb if that helps.
I just think its a serious issue in a game thats all about building and exploring and if im streaming my current world its going to corrupt sooner or later especially since the new update has even more data to drive up the file size. It NEEDS to be fixed!
