I gave it some thought and honestly, I don't think there is really a way to force it, at least in the current state of the game. It's possible that the AI starts truncating its' memory after a while and that it's hitting the prompts, since I'm not sure if it gets the entire ruleset with every prompt made. Honestly, we need a switch in-game that forces the AI to remember the rules (or to constantly remind it) so that stuff like this doesn't happen.
