A student reported this error while working through homework. I have not been able to recreate this error. Additionally, we have four other instances of this course but this has not be duplicated. Any ideas what should be looked at? We are using version 2.12.
The image is a bit blurry, but the warning messages say:
Use of uninitialized value $text in string ne at /opt/webwork/webwork2-ccd/lib/WeBWork/ContentGenerator/ProblemSets.pm line 62
