I don't know because I made a mistake or not? Because it's my first time playing this kind of game and my English is pretty bad so I can't understand the story as I should but I really enjoyed playing it. However, it seems like I might be using the cheat option too much to get items to complete all the quests so quickly that I almost unlocked everything, but there's a warning I didn't notice. at first It says "Be careful picking certain items may result in the story progression going wrong." I'm afraid this might be the reason why I can't unlock Caleb's events.
