Have seen similar threads over on the XB1 section of this board so I thought I'd post one in the PS4 section.
Going for completion, I set about finishing the fishing challenge, so completed them all one by one. I have been back and checked all three records boards, and all 12 fish have blue ribbands across them indicating completion, yet no sign of the 4th rod unlocking - not in shops or any sign of recognition of achievement or anything.
Is this a recognised bug in the game, or is it one that will spontaneously unlock after playing for a while longer?
