Something is missing in the walkthrough for Chapter 13. First, it is impossible to do everything the day after the second time Meridiana tells you that you advanced. Starting at 6AM, River @9 which takes you to 12, Peasants at 15 which takes you to 18, this puts you in the Castelans office at 21, and she is not there because you have to be there by 18 to talk, and 15 if you want to see the show. Regardless, I went to the day previous and slowed time increments [use saveeditonline to change TimeInterval

300) to (100)] so I could do the river BEFORE Meridiana showed up, which bought me 6 hours (Note, TimeInterval reverts back to 300 the next day). So the next day runs OK going straight to Dorothy for the underwear, but now the next day I don't get anything about marriage and the entire timeline stops at that point. In short, it is impossible to get to checkpoint 3-1.
