Infinite duplication

[RedRafe]

If you pick up the storage, and blueprint it down - it gets confused over the packed contents, leading to item duplication.

Steps to reproduce it:

1. Fill a WH with any item
2. Deconstruct the WH
3. Blueprint it down (or undo)
4. Build blueprint

Now the WH has been duplicated and the original item with tag is still in player's inventory.
