Hello bernabe78 thank you for your post and sorry to hear no autosaves have been made for you, despite seeing the autosave logo on the bottom right.
Can I ask why you are unable to access any of your Wrath of the Druids progress? Did you not make a manual save for 20 hours? Or do any of your saves show as corrupted? If so, do you have an image of this you can show us?
Can I also ask, were your affected saves which crashed, cloud saves? (a little cloud logo should appear on the save, in the Load Game menu, if so)
