I just confirmed a save file problem.
I had a save starting from uzhitz.
Robbed a wayfarer got his stuff.
Reloaded my uzhitz save.
Stolen items from wayfarer in my inventory.
I noticed something weird with the saves too. I failed a quest so I reloaded a save and it was still failed.
I had a simmilar thing with the heist with matthew and fritz. If they died during the quest and i reloaded they wouldnt be there
I failed the one where you had to help the Skalitz refugees. The sick ones at the monestary. I gave herbs to the worker and I instantly failed it. I guess you need to help them first? Anyway they are gone even when I reloaded.
