Done Witchery problem with Lord of Torment

I used to use witchery alot but the problem is that i want to defeat the lord of torment. I summoned the lord of torment with the torment scroll, after he is low to 250 health (he has 500 in total) he should teleport himself and the players nearby to the maze dimension. the player arrives but the torment isn't there. and if you go back to your island to try to find him he isn't there aswell. he just despawns. i asked RebornCrafter (mod) if he could respawn him, he asked the other staff but they said (atleast that's what i heard from reborn) that that's a bug from wtichery that it doesn't work in multiplayer. i did today some research on that and figured out that that isn't a bug from witchery as a youtuber (chimneyswift11) also plays Witchery on attack of the b team. he plays it on a multiple server and successfully can bring himself and the lord of torment to the maze dimension and defeat him. even at the witchery site it doesn't say there is a bug for multiplayer or anything. so what i wanted to ask if there is a way you guys can fix the problem or if you can make a spawn egg in market for him that is only useable in the maze dimension.

(Proof)

Lord of Torment - Witchery Mod for Minecraft

 

Different versions, bug may still exsist

 

if that bug exists then the site would atleast say it like other stuff that has bugs for example Devils Tongue Charm - Witchery Mod for Minecraft this says that there is a glitch/bug with the item itself and it warned on the site. if there was another bug within the lord of torment multiplayer it would be told within the site

 

Eh, I think you need to have the torment dimension chunkloaded

 

that might be a good idea but still it might not work then. i can test it out

 

Idk where, but there is already a post about all this somewhere in the forums, you could try searching for it.

 

stop still doesn't work with chunkloaders
