Not sure if I spot correctly the problem, but I believe the bot bugs when enemies attack first. What it does (as Mage) is white melee with weapon and just mana shield, no other spells. When I engage combat first, It does all the spell in the rotation correctly.

Tried stopped/restarting the robot, the problem is still there. Any idea?

Nevermind, it was a small mistake in the fight class related to mob range! You can delete the topic.
