Greetings.

I am using MCDoom in the context of Another Quality Modpack 3 on a server.

A player on my Server spawned an Icon of Sin (in the Overworld, if that matters), and it just left.
No one has an idea where it went, we have searched (including cheaty texpacks etc), and we cant get rid of the boss' health bar at the top of the screen.

/kill @e didnt help, neither did going peaceful.
Any ideas how to get rid of the boss except just unloading the mod?

Also, how does this happen? Why can bosses just walk away from the player summoning them?

On another note, Arch Maykr in the End are just sniping everything + everyone from a kilometre away, and lagging out the end very heavy, is there any way to "fix" that?

Is this happening to any Icon? Even if you summon a new one?

As for the Arch Maykr, can you confirm the version of the mod the modpack is on? Pretty sure I had updated that.

We updated ourselves to version MCDoom-1.18.2-4.2.23.jar because of something, i dont remember specifically what it was.

we have not tried to summon another icon, because we thought it useless if it just leaves.

Arch Maykr issues might be modpack-specific, as it is affected by some configchanges (not the newconfig.toml from your mod, afaict) somewhere (1k+ HP, instant respawn, stuff like that), any ideas what that could be?

The HP would be the config for sure, that's all dinkd as he's tripled most stats.

Could you try another with /summon doom:iconofsin and see if it leaves? Never seen it vanish before unless another Icon of Sin is already (I have it coded so only 1 Boss can be alive at a time in a large area...... you aren't near the overworld arena are you? It's a structure that spawns at the lowest possible y and is in the Overworld.

If this is still an issue on latest, please let me know.
