For example, one such question (from Library/NAU/setGraphTheory/MakeEulerCircuit.pg in the OPL) gives the warning at the top of the question:
Warning -- There may be something wrong with this question. Please inform your instructor including the warning messages below.
But then it correctly evaluates the problem (i.e., lets the student know if they are correct or not), but then it adds a warning after this evaluation:
PG question processing error messages
PG warning messages
------
The evaluated answer is not an answer hash HASH(0xb3284f9c): |HASH|.

I am not sure why this warning is appearing. Perhaps it has something to do with the ans_hash code as follows?:
my $ans_hash = { score => $score,
correct_ans => '',
student_ans => $view,
preview_latex_string => $intex,
# original_student_ans => $orig_in,
ans_message => ($score) ? '' : $message
};
Thanks for any thoughts that anyone may have on this matter.
Cheers,
