Zen and Knuckle Arrow Problem(Sura) BUG?

[greaver]

There is a problem with Zen and Knuckle Arrow.

Whenever the bot consumed all the spirits from knuckle arrow and then tried to cast zen and there is still a monster attacking you, the bot will try to use Fallen Empire even though you didn't set any block for fallen empire, I don't even have the skill fallen empire so it will fail requirement error message, this will cause the bot to use fallen empire over and over until the monster attacking you is killed by some kill stealer. So instead of using Zen, i am forced to use Vigor Condensation which sucks.

any solution for this?
