I've found a bug when playing the random stat version of this hack. All of my characters are showing hugely inflated stats like the attached picture. However when I browse the unit selection menu, the stats show up as normal.
I did some testing and found that this error is triggered by using the wind spell. I have the spell equipped on Lute and I am using it for the first time on chapter 6. Everything is normal until I use it. I think its just a visual bug but its really annoying
