I had an issue with my realm and had to revert to an older save. After downloading the save i cant replace ANY of my worlds at all. I keep getting different error messages too. Before i was just getting "unable to connect to realm" now im getting "we couldnt pack your world for upload. Maybe your hard drive is full?". I have 600~ gigs of free space. The strangest part is when i replace the world only the name of the world changes. It allows me to reset the world but that's it. Im paying to have this realm up so this is very annoying.
