I'm not sure what the cause of it is, but i have gotten feedback that the apk version needs to be freshly installed rather than installed over the old version. Hopefully this isn't something that will happen regularly...
Does that mean I have to restart from beginning?
It might? They haven't mentioned if it caused them to need to restart so I don't know.
I guess I'm gonna have to redo all over from the beginning brick by brick, bit by bit, molecule by molecule, ATOM BY ATOM!
