Yeah I'm with the same problem, even with last patch (1.0.3). I stopped the mission in the defend mix.rs step (I repaired the mix.rs), but after 1.0.1 the game don't recognized that I had already did all of this. So I came to the Javamatic and I have to do again the step of repaired mix.rs, after this the game bugs and the button doesn't work (and I can't speak with the doctor too).
