I have been going through the game and verifying that all the events from 0.12.0 are still the same in 0.13.0. I noticed that most of them are
extremely flexible in their starting times. I've only found 2 that you couldn't start as much as 12 hours ahead of schedule (Both were Ryoko's). Most can start as soon as the day starts at 6am even if they aren't scheduled until 8pm. This info is very useful in v.0.13.0 since the events take extra effort (like making the girls follow you).
The bug with bathrooms can be avoided. If you walk into a bathroom or toilet and there is no visible character, get the fuck out. Leave immediately. It's proceeding with the [Inception: Don't Mind Me] option that will cause your game to have to be ALT-F4'd. Just walk away instead.
