After the last lot of updates the system doesn't think that I have completed the intro puzzles. It is saying I have done 18 of 19 but as I recall I did 21 or 22 finishing with 6.2 because 6.3 was withdrawn.
Do I need to go back and do another puzzle to get rid of that notice and if I do is there a risk that the system will forget that I have done a number of puzzles since?

Thanks

Mimi
