depends, you want to see everything in the game? you probably need 2 gameplays, considering there's way more scenes than days
But jokes asides, considering some content is exclusive to some stats[like charm and innocence] and choices the player might have if you want to do/see everything you will need 2 gameplays. I always recommend going for the true ending and enjoying before going full collectionist and up every stat and find everything in this game
Alright, I had to read this and put on the sherlock Holmes hat to solve this one, since you did not state the day, lol
I'm assuming, this is day 25, after going through every possible scenario on day 21 and 22 and discover this problem is not even possible
in those day or any other.
You had to go lab>Parking lot>Sewers (Pretty sure it is also marked in the map)
I'm curious about which event let you pass time in day 25, since most events (should be all) that can pass are locked that day.
Either way, it is a good find tho, I will make sure it is not in the next version.
I will try to patch it soon and re upload (And feel free to migrate your saves, it will unstuck your character too!)
