During the quest "Ciri's Story: The King of the Wolves", my video card flipped out and I couldn't get back into the game, so I had to close and restart. When I reloaded the save point, I was at the point right before discovering the disemboweled man. I checked him out and then the quest told me to pick up some dog tallow.

However, at this point, all the dog corpses are despawned, so I have to load an earlier save to progress. It seems like a pretty bad idea to keep a separate inventory for Ciri and then not let people see or interact with it.
