The folder is inside /switch/UnleashedRecomp, simply called "cache". My firmware is 20.3.0.I did think that could be it, but im not quite sure where the cache folder is, i didn't find it. Could tell me the location? I'll also try redownloding the nro
Edit: oh and also your switch firmware version would be helpful, mine is a bit outdated now, in an early 21.0 build
