It looks like you've already completed everything.
About the key. When you advance to day 3, the game still does not remove the items collected during the first days, you will not receive the key to the kitchen drawer 06 that Ai gives you at the first meeting in the hangar, after waking up from the clinic.
So just ignore that drawer.
I'll fix this, if you skip to day 3, this drawer will be empty.
The PC in the research center (library) has no content yet.
You have already completed the research mission with Samantha, invite Ai and Jennifer in your room, press the option "GIVE" and you will open 2 options now, the 2 are Gift or Futa pill.
Cookies Quest I put "Coming soon" in the wrong place on this mission, this only goes to Jennifer with spanking.
In the survivors quest there is a warning [This quest stop here for now], you can invite them again to see the other girls during the bath, in the pool and watch a movie, the girls can fall asleep during the movie or not, depending on the movie.
Ok, I found the bug and I have fixed it.
The roles you assign during the two memory scenes with the photos on the phone are not saving correctly.
Also when you say goodbye to Sarah, she calls Mc for the wrong role, I fixed it too.
These bug fixes will be in the next version 0.26.
Thank you for your contribution.
