If the warden is angered by a target and that mob despawns, the warden will continue to roar at the target until the anger value towards the target goes below 80.
Steps to reproduce: (You don't need to create a scoreboard to see the anger value, but it can be useful visually seeing it)
- Create a scoreboard with the commands below
- Inside of a repeating command block that is always active, enter this command.
- Fly high enough to where two 1 block platforms, one with a warden and one with a creeper can be placed without obstruction using the commands below.
- Once the warden's roars use the commands below
/tp @s ~-128 ~ ~ -90 20
/tp @s ~120 ~ ~5 -110 20
The creeper should have despawned.
The warden will roar continuously until the wardens anger value towards the despawned creeper goes below 80
The creeper no longer exists. The warden shouldn't try to kill something that doesn't exist.
