My character I have the most playtime with just lost her weapon upon my installation of the Atlantis DLC on Steam, and bootup.
I know her Staff is represented in the Player.chr, because I compared it with another character and he has his equipped staff in the same spot in the file...
What's wrong with the staff data for my character?

The seed, in Hex, is "C1 00 00 00 04 00 00 00"
If I need a hex editor to save her staff, I've got one...
