Hi Runey,
I believe I have found the Problem why I wasn't able to continue the story (with the whole "you need the Human Kit", but I already handed it to Android). In my playthrough I could buy the Human Kit long before the Android requested it and it was just pulled from my inventory (as if I had given it to Android) before she even wanted it. It seems that that caused a bug where Android basically had the Kit, but it wasn't detected by Lin's story.
If you have the time, maybe check what the conditions are, that you need to unlock/buy the Human Kit. If you restrict the purchase until Android requests it (like Kali's Hard Drive), it might solve the issue. ...either that or my version of the game is weird...
I hope I didn't waste your time and keep up the good work.
