Edit:
Not all NPCs ^^

For example Echo of Sylvanas in Magisters' Terrace
Spawned and when Delete then Crash!

Please go into Crashes folder and paste the crash-log on a pastebin and link it here

Seems to be related to phasing/aura. Even tho this isn't really a persisting issue on blizzlike I can take a look anyways, but I need the crashlog
