Hi

Yesterday I played the first 3 missions, then a bug threw me back to before mission 3, I think. So I restarted the console, and had my loot and lvl up back. Then I played until mission 5, I think, all well. Today I see my character is back on lvl 2, before mission 3 and all loot gone. 

Character name is Khat. Do I need to expect this to happen again? I hope not... This would be game- or fun-breaking

Help is much appreciated
