Alright, I am going insane doing this and I have been sitting for 2 hours doing this...
...but how do I get Cassie's and Gin's Maid Costume interaction that is required to unlock Gin on Island.
I have tried every combination in my mind that was conceivable, I did the Maid Costume scene with Gin, left the town and slept, before returning to check if he isn't there, followed by checking if Cassie is in her usual spot.
I did that 3 times and more already, arriving at the lake and having seen both the scene where I snatched on Gin and where I didn't and I have always done Gin's Maid scene the day before, yet no matter what I do, I can't trigger the 3rd interaction.
Am I just stupid or am I doing something wrong?
