I played through some of the game but forgot to save, today I went on to try to regain some of my lost progress. When I try to start the Professor Genki's Super Ethical Reality Climax with Pierce, I go to the marker and see the cutscene, then the game just stops. The screen is black. It is not loading, I can move the mouse around. It stays like this. I got through this easily in my last try before I lost progress. I does the same when i try to start Genkibowl. Could mods cause this? How can I fix this?
