While in a storage item inventory (piggy bank,safe,defender forge, voidbag/ void vault) if you have a single placeable item in the storage slot, and then try to place it on the ground directly from there. The item will duplicate, a copy remains in your hand even though it was placed.

It does not seem to affect stacks of items, the number of items in the stack seems to decrease normally

System.IndexOutOfRangeException: Index was outside the bounds of the array.
