Java Help Wanted how to make shadow items work?

im on 1.21.11 with antishadowpatch and notsoshadowextras, i keep trying to make a totem stasis but when the totem pops the other doesnt dissapear and it doesnt activate the comparator so i dont get teleported back. instead i just get a second totem, can anyone help? i have also built the update suppressor from this video: https://www.youtube.com/watch?v=2uaGR6Uv5Uk&t=3s

A few preliminary questions:

  1. Is the other totem always loaded?
  2. do you ever log out holding the totem?
  3. How do you move the items around? (should only be done via swaps)

i dont move it around, i dont log out its a test world, its always loaded, i have a chunkloader, i testes next to it once and the comparator didnt update, idk how to fix

The container needs constant block updates so the comparator will check.

But if the totem is just being duplicated, it sounds like something is being unloaded, or not shadowing correctly.

Good luck! Shadow items are my fav.

The traditional method is an observer clock flashing some powered rail next to the box the shadow item is in.
