This is not a bug. The author's version of the clue is somewhat different

In the author's version there are clues in a different form, allowing to solve this issue.
The meaning of the clues is to come to Emma when she is alone. And this is usually evening in the classroom. If you are already in the classroom, you only need to go out and enter. (A condition to come into the class, not to be in it)
