I am a stupid guy.If you are using Windows, all data remains in the Windows Registry until it is deleted. Deleting the game files do nothing about old save data.
Great question. I've never gotten stuck. I've always just done the quests as they pop up rather than focus on one track or another. The reason why I am aware of the closet snafu is because so many people say "fuck finding the ball with Becca, I wanna fuck (another person)" and they end up getting stuck at the projector task.
That's why I always recommend saving every other morning in a new save slot. The game is one that is in development. Things are going to happen. Hell, in a fully-released AAA game, things happen. Save early, save often. Follow Stil996's advice to create a grandfather-father-son save system while playing.
Can you teach me how to delete it?
