Gravedigger of Drefia in party and quest mob that don't want to spawn

[Killed You]

So I was doing Gravedigger of Drefia quest in a party with my friend and at vol.3 ch.3 we had to enter to some zone behind teleport and kill Necromancer Servant(http://tibia.wikia.com/wiki/Necromancer_Servant) and rest of the
mobs from "ambush group" in that room. So we did this, my friend looted
required item and we went back and we had to wait for full respawn to aquire
the item second time (this time for me). So I'm waiting right now for
this mob to spawn (waited like an hour already), but it won't spawn so I
need gm help to spawn that mob for me or give me required item which is
Incantation Fragment (http://tibia.wikia.com/wiki/Incantation_Fragment) or
any other solution that comes to your mind.
Looking forward for staff answer or anyone that could help me.

Got answer from mail support
"Go back to the NPC Omrabas and write "lost" to get a new chance at the mission."
It worked.
