It has been discovered that on the world map you can pass through the trees and skip needed sections (including entire cutscenes). An example is skipping over where you meet Mireena, and suddenly approaching the cutscene at the cage and having her in your party without having met her. This is due to the world map trees.

For now, please do not pass through the trees. Go to the bridge leading into the forest to play the game properly. Tomorrow, I will be re-releasing the game with this error fixed, along with Mac & Linux builds.
