Simburbia keeps deleting itself.

A day after downloading and playing a few hours of a new Simburbia world I loaded the world up and it was completely broken.

 

Almost all blocks were dirt blocks with the word "update" written on them.

 

I checked the store to see if I had to manually download an update only to find Simburbia claimed but not downloaded.

 

I tried to download it again but after updating pack it crashed my game.

 

Trying again just gave me the same broken world.

 

Creating a new world also failed. It won't even load.
