I'm actually not sure! Am 90% certain my wife bought it through the Incube8 store and loaded it onto the Everdrive. I've been looking at the rom in my game list for a while though, so it could be an older version if the Incube8 one hasn't been updated. She's away on a work trip right now so I'll try and ask her when I get a chance!
I have figured out the cause of the bug after a really long time trying to replicate it. Basically I overlooked that it is possible to get kicked out if you get hooked but then don't return home until chapter 3. Since the code depended on it being chapter 2, it broke. I will fix it now and there should be an update at the link you got when you bought the game.
