[Gameplay] Cancelling out of the 'Caught Fish' animation disables fishing spot.

[Own]

So, each fishing area has a few fishing spots. If you catch a fish, hold the fish up and then shield cancel it, you can't use that specific spot anymore until you leave and return to the area.

You can shield-cancel a pond to the point where it has no fishing spots left.

I'm not ashamed to say I found this by trying to cheese 4 items out of the Arcade fishing holes.

I've been experiencing this for a while... and DAMN! I was literally trying the same thing -_-

I wanted to report this too. It's quite annoying in story mode when you go fishing for a longer while to feed your pets but break up the fishing when you see it won't be the fish you want. Sooner or later you'll have to re-enter the map because you can't fish anymore. Oh, also happens when your fishing fails.
