Puzzle steps so far
>Put Nita on floor 2, room 5 (literally don't know why, I didn't see the hint for this and this is the only time I had to cheat)
>She'll give you 800 housebux, spend this on the special gym set for her (don't fuck up like I did) and interact with her there
>Afterwards, interact with her in the water in the springs, then sit with her, then interact again
>Talk to Nita in the healing center next
>Talk to Caroline
>Interact with the teacup next to her, then interact with the following: the silver cans next to the trash can by the left elevator on the second floor, the boxes by the trash can on the third floor, and then the vending machine in the hallway on the fourth floor
>Talk to Nita
>Make her go into the shower, interact with her, then check her safe (safe will only work if she's in the shower) - password of the safe is your birthday you set in your profile
>Interact with all the generic NPCs on the first floor (save for the guard in the far back), there's five of them
>The roombas on the first floor are now dropping gold tickets, go pick three of them up (I found mine on the western side of the room, but they will only spawn after a moment where the two robots are)
>Interact with the safe (don't need her in the shower this time)
>You'll get an email, read it and then interact with Nita again
>You'll have to go to the first time you played Nita in the story in 3-6. An Adventist will spawn, kill her and you'll get a cutscene.
>Go through Nita's personal story until you get to the first battle section (you won't need to spend your daily tokens on this)
>At the end, kill the axe NPC and in that arena he's in, there will be a box. Interact with it, and THEN destroy the wine bottles at the end of the level that's to the left of the miniboss arena with the box
>Talk to Marian in the base
Currently trying to figure out what to do next, hints point at spots in the current event story so I'm playing through that now, I'll reply to my post when I'm done
