Dumped about 4 cartridges today and installed to my emunand, found the appropriate offline update files, and each game was working 100% fine. Played a level of Wolfenstein, re-upped my mystery box in Pokemon go by transferring a Pokemon to Pokemon Lets Go Pikachu, and played a level each of Yoshi's crafted world and captain toad. I unplugged my switch and took it to work (still in CFW/sx os, I didn't restart it or shut it off before leaving) and when I got to work and tried to load Lets Go again, it gave me the error that titles this post. Originally I thought it was just that one game that may not be working but I've found that literally none of the games I dumped today work now. I still have the XCI dumps on my sd card in the sx/xci folder and I can install them just fine but then it fails to install the nsp updates across the board. SD card is a Samsung EVO 128gb. Any thoughts?
Again, I didn't even restart the switch, I just unplugged it and took it with me. 2 hours later none of the work I put in before seemed to matter.
Additional info which I'm not sure matters:
-my emunand is not on a hidden partition
-my emunand is always in airplane mode and has never connected to the internet
-all 4 games worked 2 hours prior and the only thing I did was put my switch to sleep (not off) then tried running a game a few hours later
-I can still dump the same 4 cartridges just fine and I can either mount or install. Updates will not install and fail
