Game just erased my campaign progress

There is anything i can do? I was at the end of ACT II. I pressed continue today and im in the middle of ACT II, without having any missions, progression, and the map is unexplored.

I completed the Campaign on intermediate Friday but when I looked at stats it showed I didn’t complete certain chapters even tho I completed the game. At the moment I’m completing all the ones that didn’t show a medal and seems to be working fine now.It sucks I had to do it again but at least I don’t have to do the whole game over for that. Got the first 3 acts on Chapter 2 now just completed Chapter 1. Then I’ll do collectibles and hopefully insane afterwards or whatever it’s called lol
