What am i missing

I got the quest from tiperth. to kill soul collector, diana, and gnome. Did soul collector but where is diana located? Before in seal online evolution she was located out in red soil and her respawn time was pratically instant. I went over to g1 and she is not there only sandra's. I asked a player and they said oh in the middle.... but she is not there...? ideas?? did i miss something?

She's still in G1. If she's not there that means she was killed and her respawn time is quite long.
