On the Subject of Forget It Not

This forget is quite literal.

This module presents 10 buttons, labeled 0–9, a screen which displays the current stage of Forget It Not, and a screen which displays a number. This number changes every time a non-ignored module is solved. Also, if the module’s background is not yellow, you may be looking at a different module.

This module can only be solved at the very end, by inputting every number on the screen that was seen earlier.
