A player has developed AI agents that can now fight each other in the game, testing various battle strategies and discovering some bugs in the process.

The best thing it found is a bug no monster fight ever showed. A party's plan is its leader's, and a dead leader's next goal is to find a healer. So when the leader dies, the rest are handed that goal in the middle of the fight and follow a ghost off the field.
