Alas, none of my save files are salvageable. Did not have one from before I took to the river, around which point I assume the corruption occurred. Back to square one .....
Since moving into Occupied Lands all nests, boxes, etc. are empty (although caches are not). If I return to previous zones, contents that were not taken from boxes are still there. Has anyone else encountered this problem? Thanks. (Running game on Windows 7).
