Shin Megami Tensei III: Nocturne HD Remaster had issues when it debuted in Japan about a month ago, as the game suffers from a few technical problems.
Good news however, as Atlus is aware of the situation, and is now looking to improve the HD release, and announced in a blog post today that a patch is planned.
Atlus is looking into the behavioral speed in specific places, in addition to some phenomena thought to be caused by bugs and says they will follow up when done checking the issues and making a list of fixes for an upcoming update.
