Workaround For Storage Box Bug

[nextgengranny]

Don't try to stack items in the storage box. Stack them in your backpack, then move the stack to the box. It's a pita, as you have to do that every time you want to add an item to a stack, but it's better than having the items disappear.

If anyone has found a more elegant workaround, I'd be glad if you'd post it here.
