Not for me, it doesn't.Also, I didn't know mafia would be doing a best guess:
Wrong. KoL says,You acquire Thwaitgold grasshopper statuette (2)
You acquire 2 Grasshoppers
Taking 2 statuettes from display case, KoL says:
Thwaitgold grasshopper statuette (2) moved from case to inventory.
Putting them into my closet, KoL says:
You stored 2 Thwaitgold grasshopper statuettes in your closet.
Taking them out again, KoL says:
You acquire 2 Thwaitgold grasshopper statuettes
Putting them into the display case, KoL says:
Thwaitgold grasshopper statuette (2) moved from inventory to case.
In all cases, KoLmafia tracked the item movement perfectly.
I see no bug.
