I'm looking through the code now, the requirements for this event are as follows:
Lin's friendship is exactly 26
Android's friendship greater than 25
Android's friendship is not 27 or 32 (when she's missing)
and Android has the outfit.

So I've looked into it, requirements are correct it didn't work tbh for some reason, so I decided to level up everything from Android and lin and it started working, so far I have completed all tasks and stories now just patiently waiting for V0,13.
I love the story so far and I hope there will come more stuff for the side characters and Autumn
