In which gamemode were the endermites created?

Enderman only react to Endermites randomly spawned through throwing enderpearls in Survival-Mode.

I have two working Enderman farms in several 1.12.2 worlds without any issues.

it works fine for me in 1.12, in 1.13 everything should be fine like what @Stefan B. said.

Whether the endermites are targeted by an enderman is determined by the presence of the PlayerSpawned tag on the endermite.

Endermites created by

/summon endermite

or

/summon endermite ~ ~ ~ {PlayerSpawned:0}

are not targeted by endermen;

those summoned by throwing ender pearls or

/summon endermite ~ ~ ~ {PlayerSpawned:1}

are targeted.

Cannot confirm in 1.13-pre10, see attached screenshot.

Works fine in 1.13-pre10, did you spawn them with a spawn egg or command? If through command, which one? Endermen will only attack enderpearl-spawned endermites.

Thank you for the help. The original endermites were spawned in survival and named but disappeared yesterday, I did spawn them in creative. I just spawned a new in survival and the farm is working again. thanks again

@unknown: Endermites are attacked by endermen if they have the PlayerSpawned tag set to 1. If endermen do not attack endermites spawned by ender pearls, that means that PlayerSpawned is 0, and that is a bug.

The command I used was

/summon endermite ~ ~ ~ {PlayerSpawned:1}
