I made some fix:
You can trigger Celine's peeping event
Peeping events doesn't crash anymore after a big number of peeping
You correctly go to the villa's hallway when you go out of marcella's room
Sandra's intro even has a requirement in the achievement board, and it's more easy (can be triggered during the night)
I also added some little new things:
The infobox Write information when you enters a patreon code to tell you what you've unlocked (people though nothing happened because it wasn't visible)
I added a black background to the sentences of infobox for more visibility
Infobox's messages exists for 5 seconds instead of 2
New Message when a character level up!
