Thank you for reporting these bugs and for your kind words :)
We just uploaded a fix update. Once you download it, you should be able to load your save and resume playing Chapter 4 without losing your progression.
Good mystery hunting!
Thanks! That fixes that issue, but I'm now stuck at the end of the Cathy scene with !GotoContinueButton;;;GetTicket
Thanks for catching that too. I just uploaded another fix update: you should be able to resume your progression without any loss.
Thanks again!
