When one of our teachers attempted to crosslist a class (B) with the parent class A, everything in B disappeared: teachers, students, etc. There is also no longer a button to crosslist or un-crosslist, the button to add People (students) is greyed out, and the class shows up under past enrollment even though the term reads Q4. I'm wondering if this could be a class uploading issue from Infinite Campus, and if the class could be created again. But this is a very weird issue we haven't seen before. B is not showing up on the A's list of sections, but two other classes are.
