Okay, something weird is going on.
I have a LOT of titles installed on my SD card. I'm starting to think there is some weird limit at some point, and titles start "disappearing" without being uninstalled -- which is a pain, for reasons I'll explain.
- Collection of SAGA, Collection of Mana, Castlevania Advance Collection, and Giana Sisters Twisted Dreams (?) all "vanished" from my home screen.
- None of these were visible in my "redownload" list, but ALL showed "purchased" on the game's individual screens.
There was literally no way to install these titles. Perhaps the files were corrupted, but I couldn't find system option to repair files/installations.
Suspicious that there was some sort of issue with the installed files, I removed the SD card and rebooted. I went into the eShop Redownload list and noticed two things:
- Castlevania Advance Collection and Giana Sisters were both listed in my Redownloads. The redownload button added them to my home screen and started a fresh download. Interestingly, I could immediately play both titles, even though the downloads were nowhere near complete -- once the Redownload was initiated and the link was added back to my home screen, the Switch appeared to be able to use the existing (formerly hidden) installation without a problem.
- Collection of Mana and Collection of SaGa did not appear in my Redownload list -- however, the eShop title pages for both games had a DOWNLOAD link instead of PURCHASED, and I was able to "reinstall" the titles from there.
After reinstalling, I archived both titles -- and now they appear in my Redownload list.
In summary: at least 4 installed titles "vanished" from my Home Screen (and the "uninstall software" settings menu) but could NOT be reinstalled as the Switch seemed to know they were present, albeit inaccessible. The only solution was to remove the SD card and attempt to redownload the titles directly to system memory. Also, the two Square titles still do not appear in my Redownload when uninstalled, but they DO have the Redownload option on their title menus in the eShop - after installing then again, the Redownload functionality appears to be fixed.
Has anyone else had this issue?
(I did switch to a new memory card in December and had to redownload everything -- maybe a few titles had issues when downloading and didn't complete properly?)
