Over the past few days, Shin Megami Tensei IV has hung for a few seconds and then crashed (forcing me to shut down the 3DS) a decent number of times (at least 6, enough for me to think it's not a coincidence) while loading the save data screen. This only seems to happen after I try (but not nessacarily succeed) to recruit certain demons (like Quicksilver (or Zombie Cop though Scout+) and Kabuso, but not Azumi, and I can't tell until after I recruit them and eventually go to save), but I've also managed to make it crash while trying to enter the 'load a saved game' screen from the title screen. I'm on Cycle 2 and this didn't happen in my first playthough, and this seems to only occur while I'm in Chiyoda (though I can't account for all the cities, since I've only just reached Shinjuku).
I'm running system version 9.4.0-21U on a North American 3DS (the Luigi's Mansion SE one).
Shin Megami Tensei IV is the downloaded version and has the Version 1.1 patch.
Has this happened to anyone else, and is there a fix or a good way to avoid this?
