and here we are... over 8 months later from the OP timestamp, and this bug has hit me two times out of the last four games. I tried turning off and back on tutorials, which did not clear the problem for me. i actually have not made it all the way through the tutorials as far as I can tell even once, though once I did get further along than this section. tutorial part 8 I believe) is this specific part. Think i might just give up and leave tutorial turned off. going to create a new game now for the 5th time, and make sure I don't get ahead of the tutorial, maybe see if I can get through them without them breaking.
