1.19.3: Bosses not despawning if Chunks are unloaded + Mobs like Wither & Warden not despawning at all.

[0x484]

Issues with the "Despawn when far away" function:

1. My Bosses are not despawning when they're in unloaded Chunks. To be specific, sometimes they do despawn but most of the time they don't. I am not sure if this is a bug with the Boss plugin or my Server or if it's even possible to despawn since the Chunks are unloaded.

2. Boss Mobs like the Wither and the Warden + maybe others (I haven't testet them all) do not despawn at all which im pretty certain is a "bug" with Boss. Is it possible to make those despawn as well?

Boss Version - 4.7.4

Have you checked if you have persistency disabled?

Yeah, all Bosses are of course set to "despawns"

Normal Bosses do despawn, I can test this when spawning them and changing Gamemode to Spectator. With Withers and Wardens, this does not happen. (Alltough as said, normal Bosses also do not despawn when a Player gets killed and the Chunks are unloaded)

Hey and thanks for asking!

1. Unfortunately that is not possible as of right now. We would have to open unloaded chunks on your disk using expensive methods involving NMS. That would decrease stability of the server in case the chunk got loaded in the very moment we would be scanning it (such as by a random player teleport). Bukkit does not provide this feature either.

2. I do not think Wither/Warden despawn on vanilla either, that is because they are considered a "boss" mob in Minecraft. To despawn bosses I call the vanilla server's "setRemoveWhenFarAway()" method, beyond which I have no further control.

Thanks and hopefully that answered your questions!
