Any change that you make should be reversible.
No data for the student is ever deleted. So you can rtemove a problem
and then reinsert it again later. But it will need to be in the same
map and get the same id number in that map.

Most changes are fine, the random number generator can causes concerns
adding <foils> to a problem or changing it to or from unused can chage
what a students correct answer is, but changing the text of foild or
other portions should be fine. Adding more &random() calls after all
of the other &random() calls should be fine.

This is not allowed and may cause serious issues with this particular problem.
If you want to add parts to a single part problem you can do this, but
it will look like a fresh new problem to the students.

They can also be made when a student has attemted the problem, but
their status on the problem will be reset to unattempted.
