The posted location for Rolfosteus Canningensis (AKA 'Rolfo') is near the pillar rock on the right of the deck but from facing north on deck, not on the right edge. The same for Purple Queen.
If you walk sideways to left end of the same deck and cast straight ahead right near the rock in front of you (about 80 feet) both fish seem to be there too. In fact I have caught more Rolfosteus Canningensis there than by the pillar. I have even caught 2 fish in a day a couple of times.
Anyone else caught it somewhere else on this island? Still no S here though! Last one for this island too!
