I reinstalled the game and started over and it gave this error.
```
I'm sorry, but an uncaught exception occurred.
While running game code:
File "renpy/common/00action_file.rpy", line 372, in __call__
File "game/scripts/core/checkpoints.rpy", line 24, in checkpoint_name
IndexError: list index out of range
