I have just noticed when you say that. Now this is important so please keep it in mind. DO NOT use the Inn in Cindalia City to rest during the invasion of the Wild Beasts, or you will get stuck in that event. Or for the best, just do not use it until you arrive on another city. And please prepare more than one save files in different moments, in case something bad happens (especially in Cindalia City during the invasion). Sorry for this bad issue and thank you for your understanding.
