I may be found the way to save your corrupted character (I am talking about game won’t load after crash with corrupted character):
So you go into your character save directory:
*For local people:
**C:\Users\USER_NAME\Documents\My Games\Grim Dawn\save\main_CAHR NAME
*For steam-cloud people:
**C:\Program Files (x86)\Steam\userdata\NUMBERS\219990\remote\save\main_CAHR NAME
And then you delete map.dat in:
It helped me. Please report success/failure. Thank you.
