So I just purchased the game and expansion a few hours ago. Started a new game. And the very first enemy I encountered. A wolf, stands back up after dying, but now can't be targeted, and chases after my party indefinitely. After finding an end around that. I've gotten into the second map of the game. In some old ruins. and pretty much every single enemy in here. Gets back up after dying, but is no longer targetable. I need to know if there is a fix for this. Cause this is jsut extremely frusterateing and has pretty much brought my game to a complete halt. Also in these ruins I'm getting large white squares replacing sections of the background. I really hope there is some manner of fix for this.
