I have gone to the area on the quest..the quest is Cleaning Up the monsters.. I killed monsters that where in the area that it was in.. that had told me was getting credit for the quest.. told to kill 10 Oestrus merman..when I got to the area.. was killing flyaway fish .. it told me i killed the 10.. but when I tried to hand it into the npc .. it wont give me credit for it.. says it is unfinished.. what do I do?

did you killed the right ones? did you go to the location defined in the quest log?

There are to 4 different mermaid in that area.

Also you will get an counter after you have killed the right ones.

I believe I did.. it did the count for it.. told me to hand it into the npc but when I go.. it doesnt do anything

n.m. I got it to finally give it the quest in
