Well it happens when the enemies are too close, allies are a bit dumb and try to use the fastest attack :O You can teach your allies more range attacks so they'll be more likely to use these. Just remember to never teach them the explosive ones.
Thanks! love the game by the way.
Thank you!!! I'll try to make the allies even less dumb in the next updates ^^' they already come from a looooong road of dumbness X'D
