Echo of Sylvanas
Sylvanas ascends towards the sky, pulling all of her enemies below her. Her calling then summons eight Risen Ghouls in a circle around Sylvanas. A shadowy link forms between each ghoul, and the area behind each ghoul fills with shadows. The ghouls then march mindlessly towards Sylvanas. When a...

there is an NPC that when killing him freezes the server.
giving this error on the server:

C:\Users\Administrator\Desktop\EC\emucoach2020\src\server\game\Entities\Object\Object.h:948 in WorldObject::GetMap ASSERTION FAILED: m_currMap [0xc4254] [0x5f8948] [0x45c200] [0x38cf80] [0x275d8a] [0xb3db3] [0xb3c14] [0x4030ef] [0x658dd9] ACE_Task_Base::svc_run()+0x41 [0x88181] ACE_Thread_Adapter::invoke_i()+0x69 [0x886c9] ACE_Thread_Adapter::invoke()+0x67 [0x88647] configthreadlocale()+0x92 [0x214c2] BaseThreadInitThunk()+0x14 [0x17034] RtlUserThreadStart()+0x21 [0x4cec1]
the NPC has these characteristics when giving the command ".npc info": ID=54191

But the NPC is a "ghoul" that Sylvanas invokes, this NPC is only the one that appears next to the clock, when you kill him the server freezes.
As a temporary solution, just giving the command in the ".NPC del", to avoid all this, it is only to erase this ghoul (of all those it invokes), prevents the server from freezing and allows you to finish killing sylvanas correctly.
Except that you have to review later some powers that Sylvanas launches.

Risen Ghoul
Risen Ghoul is a level 35 - 80 Elite NPC that can be found in End Time. In the NPCs category. Added in World of Warcraft: Cataclysm. Always up to date.

--------------------------------------------
a bit before getting to face Sylvanas
also there are some NPCs who are dead and still continue fighting and taking life points. Being dead, they follow the character like a corpse lying on the ground (they cannot be hit because they are dead).

but it is solved momentarily by giving ".npc del" on them and deleting them from the dungeon.
