The exact thing in the same place has just happened to me. Turning off console and turning back on and the continuing game doesn't work either, I assume beside it's loading in the same spot. I'd been warned to save in multiple slots so hopefully I can resume from not too far back otherwise I need to start again! Very frustrating!!
I downloaded today's automatic upgrade previously btw
Hope to see a fix for this issue
Annoying bugs on what is an otherwise fantastic game
