have you made any changes to state #1? That one is hard-coded as the death state
If state is unchange we need more info on what happens in your battles and how you try to kill the enemy (which skill you use etc)
EDIT: and I just saw that you deleted troop #1 and #2 - for troops that don't matter, but if you did the same to states (where #1 is hardcoded for death) or skills (where #1 and #2 are hardcoded for attack and guard) that will cause problems. those three cases have notes by default to inform you about that
It's been a weird while. I've been so torn down that even playing video games has been something I avoided. But I shouldn't forget two things. One, I love RPG Maker for a reason. Two, only way to eat an elephant is a bite at a time.
