After exiting a Nether portal, Shulkers no longer travel back through the portal when their shell touches it

The bug

See the attached vidcap. The shulker opens and doesn't got through the portal, I switch to survival long enough for it to open fully and shoot at me and it still doesn't go through the portal. This is not a portal cooldown issue. I've had this shulker there for many minutes.

How to reproduce

  1. Download the attached world (

  1. )

  2. Spawn a Shulker on the side of the blue wall closest to the Nether portal

  3. Wait until the Shulker opens its shell
    → ✔ The Shulker travels through the portal

  4. Enter the portal

  5. Spawn around a dozen Shulkers inside the portal in the Nether

  6. Return through the Portal

  7. Find a Shulker attached to the blue wall and wait for it to open its shell
    → ❌ The Shulker doesn't travel through the portal

Hi, can someone look at this bug?

May I ask whether you have actually ever entered the nether portals yourself showcased in the video? This is required as the nether dimension and chunks need to be loaded in order for entities to travel through them. Thanks 🙂

Yes, this is a world I play in regularly. I've been to the nether and back many times. 

FWIW, it happened again recently. I found another shulker in my farm that wasn't going through the portal. If it's of any import, I'm running this world on realms.

This is a shulker farm and it recently stopped working. The shulker in the center died or teleported before splitting. I determined that the reason was that shulkers stored on the nether side of the farm for restocking were occasionally coming back through the portal and lowering the split probability of the central shulker. I think this is one of those shulkers.

Hi, I know it took me a while to respond to the last question, but I was wondering if anyone will be looking at this bug.

Hello, can someone look at this bug?

Cannot confirm in 23w42a in single-player. (I am unable to attempt to test this on a realm)
