I'm sure i set something up wrong but from what managed to do I can get 1 of the 5 bags i made in world. I'm using kubejs to get the lootbags to work and only used the basic recipe to get the bags "working",
from testing removing folders lets another bag show up and all bags work. A well with testing found out that removing from folders does nothing. (folder name was also changed and that did nothing)
pic shows the files and JEI with the 1 active bag as of when i took each screen shot (as well as the folder name change)
