To Fight A Fishback requires you to go to certain spots around Limsa and gather Pixie Remoras. The first 2 spots work fine (although, my friend said the second spot didn't work for him). The 3rd spot, below Skull Valley, seems to be bugged. You're suppose to get a message saying "Your instincts tell you there's a school of fish here" when you've hit the right spot. I did it over and over on the spot, even places around the marker and still no go. I abandoned it and tried it again the next day. This time, the 3rd spot worked. The 4th spot next to it worked at all. The 5th spot requires you to go east of Bloodshore. Of course, this spot is broken now. I really don't want to abandon in again just so there can be a chance that it will work properly this time. I've tried all around the area and I don't get the message at all.

Please take a look at this quest. I want to get my skills and I can't until I complete it
