Correct if the open date wasn't set they can't see the problem. (but
they were open as you stated later)

Couple of things here

1) Was the problem republished?
2) Did the part numbers change?


If 1 and 2 are yes, (for instance part '1' was changed to part 'two'
in some.problem in week1.sequence)

The data that is stored says the user got
part '1' of 'some.problem' in 'week1.sequence' correct


If the problem now only has part 'two' then the user no longer has the
problem correct.


The intructor has a couple of options in this case

1) go into docs, and set the version number to user for this problem
   to the previous version with the old part numbers.

or 

2) revert the part numbers back and republish the problem


Note that there is a large red message displayed when the system
detects that you are changing the part numbers in a published problem
when you go to publish it again. Please heed this message.
