I reported this earlier, where enemies would seem to get an infinite turn loop when attacking, but I ran into it twice tonight and both times it was linked to enemies attacking my monster with Petra and Aes attuned, when the enemy went first. Two logs attached:

In both cases, the enemy’s turn kept coming up; it would take an action, and then continue to take actions to attack my herbling until the herbling was no longer a valid target.
