Oh I didn't know that.
I now confirmed newly spawned shulkers sometimes teleport after an initial attack with a Sharpness 25 sword.
So, okay, it works as intended. Sorry
You may have to make shulker duplicate by a shulker bullet.
I added two more examples tested in 1.20.2.
I used a sword with Sharpness 25 to prove shulkers have more than half health.
confirmed in 1.19.3.
This is a serious bug for simple shulker farm (manual killing) and needs to be fixed.
No, because MC-230971 is about shulkers below half health. The problem here is that shulkers can teleport even if they had full health when damaged.
Thanks for your comment. Do both villager sell a map for 6 emeralds?
I wonder if the discount is a bug.
Imao, the game should have the data of "why the chunk is loaded". If the chunk is loaded because there is a nearby player, hostile mobs should be able to despawn. If it is loaded only because an item entity is sent through a nearby portal, hostile mobs shouldn't be able to despawn.
