My class is working on the AP Create Task right now (Unit 8). In stage 3, the recommend stage to develop their apps the list declaration with numbers and the list[i] blocks are missing. If you are working on the Create Task, be sure to have your students check to see if they are present. They usually appear between the strings and list.length.
This could be a HUGE problem for students that only use blocks as they may not know the syntax for making a list or referencing list items. Note, I have sent in a bug report, but if you are seeing it too you may want to do so as well because of the importance of the task. I hope this is helpful to others currently working on the task.
