So, I've been trying for the past hour to use the in game loot chest editor (with the enchanted loot chest item) and couldn't figure out how to add new items. I can add loot groups, but when I click "Add/remove loot" or however that button is called it just lets me add an item named "#X" with X being the number of that item in the creation order starting from 0 and set the weight of it but dosen't let me set that item as an actual item. Is there anything I'm missing?
P.S. Yes, I only get dungeon loot from loot chests even tho i added a group with a weight of 1000000 and it says "100%"
