I'm in Spring of year three on the switch (single player), and I finally caught some fish I'd been after for ages. However, they were not updated in my collections, and when I checked the other tabs I found that some other items also had not been registered, such as the copper and iron bars (which I have definitely crafted before). I tried crafting some of the items that were not registered, but crafting and picking them up also did not register them. There is no error message. The game is updated to the latest version. Edit: I reinstalled the game (twice) and it works now :). I also think I made a mistake, I assumed all items got registered the same way gems did (finding it registers it), but it seems that is not the case, so that also explains a few of the gaps in the farming section and the fishing section. I'll still have to re-collect some gems, but that's not too big of an issue. I'm glad I can still try for perfection!
