When I purchased the game after enjoying the Demo for about a week (I was broke till payday), I found that included in my inventory was the ArchShepherd’s Staff(Think that’s the name, the one with the sheep teethmarks). This is despite not having earned it (Can’t even play that level in the demo.) Later on, when I did earn the staff, I had two of them. I equipped them both, naturally.
Coming back to it at another time, it was the next day and I’d played a few battles, I noticed that the person I had equipped with the bugged staff no longer had a weapon. The mystery staff had vanished.
Edit: Using Windows 7 and Game is Steam version 1.0.51
Edit 2: Added my Demo Save so you can see what I’m loading from.
