I have the same problem with the Calculus Padge, already raised an issue but I don't think that has high priority. There just seem to be a few loose ends, just like the videos that are no longer available (search for "oboe"), but fixing that takes more defensive programming. Since 12 (my time CEST) I did two exercises and got the Refresh message, after that on every items and there are 6 more Lightspeed badges out there that I know I can get if things work (things work fine on the  second account I tested this with, so it has to do with my account/history/database entries).
