Then login to your gm account with right click command.

Click the npc to show the first dialog. then right click on it to kill it.

The npc dialog will remain, then use @load to remove it.

After that try to load that npc again using @loadnpc.

Your map server will crash. no error will be shown on the map server, it will just automatically close.
