Ive noticed a constant issue I have not been able to get around.
When filling up all pouches the script will withdraw a full inventory of essence, This will fill the small ,medium, and large pouches without any problems and leaves 5 essences left over. The script will then fill these essence into the giant pouch but will not withdraw more to fill into the pouch.
After the large is filled the script should withdraw more essence then attempt to fill the giant pouch.
