its cause of the bot is trying to find a cluster with more then set mount of creatures lets say its hard coded to find at least 3 enemy's or more in a cluster and for some reason in trail and enemy summoned from events it wont detect it... i noticed that for a few other spells to like blizzard and so on for wizard but i kinda fixed those using a very stupid method my self.. just removing the cluster detection .... but then its not relly casting it "smart" anymore
