Likewise lost everything. I had completed everything save the Noble's daughter, but I had reloaded to try not to break the Dragon's egg. When I got back to town and the Herbalist had no idea who I was i checked and saw all my journal entires had vanished, even though i still had all the quest items. Also that item dissapearing bug is annoying. I didn't notice it until halfway through my playthrough, but once it started it was like gremlins were constantly rifling throuigh my stuff, even equipped items. Pick something up, put it down, *poof* gone.
