Bug I had that i cannot understand for the life of me: For some reason, after i gave her the sex toy, Misaki follows me around wherever I go and refuses to leave me alone.
Been digging through the code looking for this one, but the only place in the code that sets her to follow you is to ask her to follow you.
That said, the game is huge, and its done stranger things, so it's possible the game did some kind of voodoo to cause it to happen too. Is there any chance you could share a save file? Might be we can find where it originally triggered that way and figure things out for you.
Lost the original save by now, but I did some save editing after my first post(please forgive my sins) and figured out that, yes, she was in fact flagged to follow me. I just unflagged that, but again, the only thing i did was give her the sex toy, and I have no idea how she got flagged to follow me.
