Steam user here. I love the game. All the princesses are cute and the CGs and Animations are amazing. Roaming NPCs sometimes morph into each other(?) Like Amelie and Michael or Niuya and Michael would be standing in the same place and blink back and forth between each other. Talking to them will always result in me talking to Michael. The overworld map also turned completely black. I could see signs, castles, and pockets of water but nothing else. It went back when I entered and exited an area.
