Trying to solve a rather frustrating issue here... I used hackingtoolkit3DS to extract a decrypted .cia of Fire Emblem Fates to look into the file structure of the game without editing anything. When the time came to rebuild the romfs, I noticed this: Warning: Spoilers inside! The RomFS that was rebuilt with RomFS builder is smaller than the decrypted RomFS. I initially thought nothing of it and rebuilt the .3ds and converted it to .cia and put it on my system. But then I loaded up a save and noticed this: Warning: Spoilers inside! Suddenly I really am experiencing the Invisible Kingdom, even my own units join in on the fun. Viewing any character model just causes the entire system to crash and reboot. Is there a step I'm missing here? Is there something extra I have to do to the rebuilt RomFS?
