Thank you for making awesome tool!
I generated Inventory Bags by ‘set inv/0/items “inventory bag”’, but nothing happens when I right-click the generated Inventory Bag item.
Do I have to complete the quest which rewards the bag to use this item properly?.. (I guess it isn’t though)
Or is there another real Inventory Bag which has different name? (inventory sack doesn’t work) 
Edit: dropping the bag item and loot again unlocks the additional inventory up to 5.
