It also looks like it's trying to open the Large, medium, and small pouches all at the same time after the first craft. which means the large pouch sometimes doesn't get fully emptied if the alter gives you too many variety of runes.
@Khaleesi Not sure if this has been noted yet, but when doing ZMI, if you have all 4 pouches, when crafting at the altar, if you don't have 12 free spaces left to empty the giant pouch, the script doesn't re-empty the pouch and you end up teleporting with leftover essences in the giant pouch.
