I've had moments where I know I've done something in the past, but, cannot recall which game it was where I did it! The best part is that I'm sure this happened to me relatively recently, but, what was I even working on? Oracle of Askigaga? This script? What was I looking up, even?
*third worst memory*
*Edit: All I remember is double-checking Okiku and Konae for whatever reference I was looking for.
