Amazing game! Just one problem... – Fishing Paradiso Review

I think I’ve found a terrible but in the second quest for items for the spaceship, the one for the angels tears. I have caught 10 fish of the species I need, over hours, and not a single one of them was above D level, which means this might be a glitch, and finishing the quest is impossible. Please fix, or make B ranks more common?
