Hello! On my character CatsQuest, I've killed 5 of the Nine-Tailed Fox located in Korean Folk Town Hidden Street: Moon Ridge. The quest (Retrieve a Soul) is still not registering that I've killed it, and not allowing me to turn it in. On the Quest Helper, it says 0/1 Nine-Tailed Fox, but on the Quest tab it says 0/1 Old Fox. I'm wondering if this may be why. I tried to search Old Fox to see if it was a different boss, but only found the Nine-Tailed Fox exactly as the ones I've killed. Thank you for your help in advance!
This happened to me too. If I remember correctly you have to forfeit the quest and try it again and it should work.
