Disregard, the Ani Dead: Idle in the commands was causing the issue, removing it causes the enemies to fade as they should.
Is it possible to somehow replace the animated battler with a static image - for instance if the enemy is dead, or are any of the "death animations" usable with a simple command? (i.e. Ani Dead: Fade ... or something to that effect)
Looking at your video, I see one enemy that fades away upon death, and another collapses into pieces. Using a couple of Aekashics' new battlers, and it seems like they just stop moving and stay on the screen when dead.
If I want dead enemies to go away - would I have to edit the _ske file myself to create an animation for it if none exists, or is there a simpler way?
