Master Angler achievement?

[Nightweaver20xx]

Stardew Valley Checkup says I have completed the Master Angler achievement, but my achievement list doesn't have it as completed, and Willy hasn't sent me anything yet. What gives?

In the collection menu there's a tab specifically for fish you've caught, open that and see if there's any unmarked icons.

Oop, nevermind, SDV Checkup was counting fish from the Expanded mod. I still need to catch the Octopus and the Puffer Fish, which I will do very soon since it's almost summer in my game. :p
