nvm the placed ones disappeared and the item ones worked ♂️
there's another placed one in the enderman farm of the island
the one that was placed fell into the void
when I was trying to consume a karma crystal, it appeared in front of me, coords are X: -605 Y: 100 Z: -5 on the top island. some are in a chest and one is placed.
(sorry I didn't use a format or anything, I completely forgot what it was)
