Tried to create a weapon armor datapack for stun armour attributes for the mod "TerraFirmaCraft". However, the item ids for equipment from that mod contained "/" slashes. This prevented me from creating .json files with the exact ids of the items I wanted to edit (which is required according to the wiki of this site)

May be changing how datapack is read by the mod so that the item id is taken from a parameter within the .json file itself instead from the file name?

Same issue as #1146, actually

Fixed on 18.3.7 (1.18.2) and 16.6.3 (1.16.5), Check updates channel in our discord to see how to arrange the folders in order for this to work
