I spent a while trying to finish all of the cat's stories before going to the final place at the end of the game, and I did. Sadly, after I enabled NG+, it appears the game has broken.

Number one, there was no intro when I accepted their job offer (Not sure if this is bug or on purpose)
Number two, all cat's suddenly had their final cutscenes renenabled, so I was able to talk to all of them in the lobby and none of the quests had been undone, so everything was still complete..
It appears the NG+ stuff is working, as the grave and such were usable and I ended up at the apartments once before leaving the game due to an obvious issue.

What could've happened? How can I fix it?
