OP has been updated with 1.8
Unfortunately, I have reworked how my scripts convert RPGM variables and switches to Ren'py effectively breaking all save-games. This may have introduced some bugs in the story-flow. Let me know if you find any.
While there is a rumor about an 1.8.1, I released this anyway so more people can test it
In regards to the possibility of an 1.8.1, I suggest making a save at the pool party scene. Any later save may have issues depending on where Deepsleep changes the story. Unless there is a game breaking bug in the conversion, that save should keep on working.
