I noticed I was struggling a bit with this one but at first I thought it was me making the mistakes. Usually they're targeting the first pet in the party lineup but this one did not. As the bottom of the combat log shows, Freiza and Blazehowl were the ones moved from the last turn to preempt the explosion while Reef Guardian was left where she was. Why, then, did my pet at the top of the map, who was always at the top of the map, get slammed with the exploding shards?

Annnnd that's when I noticed that his target reticle on the right side is missing.

This should be fixed.
