Can you tell me about all the decisions that you made up to that point? Which man you sided with, whether or not you collected the evidence, and whether you had to sneak into the meeting (versus being invited)?
IIRC I sided with the Wen, I think I collected evidence, and I snuck in. Sorry that my memory isn't the best. I'm in the middle of a parallel playthrough and will see if I can reproduce it. :)
Side-question: Is the game intended to be played in one sitting, or are you supposed to be able to close it and continue it later?
I was able to repro with a substantially different path. One correction: I chose Wu on both playthroughs, but it looks my path/options changed due decisions that predate that. This time I had the softcore option, but did not have the option to sneak in or take evidence. I still ended up on the same dead end.
I also found a minor conversation loop that I didn't notice before in my first conversation with Fang.
I'm really astonished by the narrative complexity and think this is really special, so I hope highlighting flaws isn't too much of a downer.
