Flexible Survival

I try hunting Math Teacher on 2 different save files.
But I can not find her and get the : You don't think what you're looking for can be found here... System Message.
Confusing because I am at College Campus in game and I remember that monster being there in the past.. .

EDIT : Still confused because VthisV lists Math Teacher on College Campus; but the Infection Terminal Does Not:
viewtopic.php?f=4&t=14&p=69&hilit=Math#p69

Help??

Most likely, if the Math Teacher can't be found on the campus it's probably because it was removed to add space for new content.

Edit; Yup, just checked- the latest update removed the Math Teacher.
