hi SChin,
thanks for getting back to me on this concern.
saw your save file request so i just tested if i could access the interactive cutscene again on one of my saves and for some strange reason, the issue got fixed!
i entered through the Boiler Room and got in the Manor again finally
after i reported the issue here, what i did was do one of my other pending quests (kill Beina) then logged off
not sure if all it needed was a device reboot but thanks a bunch for looking into it, hopefully it won't occur again for me or anyone else c:
cheers~
