Alright, I sat down today and I fixed the problem with respawning enemies. I also did a few additional minor things and fixes that I came across.
This version requires Blizz-ABS 2.85. But Blizz-ABS 2.85 is not out yet. There is a bug in Blizz-ABS that causes this script not to work properly. Basically, you can edit Blizz-ABS code yourselves until winkio puts up the real thing.
Find this line:
elsif character.is_a?(Map_Enemy) && !character.ai.lifeless?
and change it to this:
elsif character.is_a?(Map_Enemy)
This fixes a problem that when an enemy is killed and the G-Master processor changes, the enemy won't respawn until it is switched back to the player who killed the enemy.
