Sounds like my Unifi experience with the old CloudKeys that liked to brick themselves if the wind blew in a way they disliked. Everything still ran fine, but I couldn’t manage any of it till I factory reset it all. I think it ran like that for 3mo before I could be bothered 😅
MH4U (on 3DS) is what got me hooked! Still maybe my favorite, it just had an obnoxious amount of content. Still have my CirclePadPro around somewhere…
