I ran into continuity errors while starting a new game. The new into cutscene states that it was 16 years ago, then when talking with Ellen, she says 14 years, and then during the scene with Lin talking to Kali in Kali's room, Lin says 2 decades.
Let me clarify. What I found was not a bug, but a continuity error in the writing. When watching the cutscene when starting a new game, when the grandfather is talking to his maids, the caption states it happened 16 years ago. Then, when speaking with Ellen during one of her scenes, she says she started working for the hotel 14 years ago. After that, during a scene where Kali is wearing the maid outfit and speaking with Lin, Lin states that Ellen started working there approximately 2 decades ago, which she shouldn't know in the first place since she wasn't even working at the hotel at that point in time.
Hopefully this clears up my previous comment, if not then let me know so that I can provide screenshots and possibly event numbers to narrow things down.
