Along with @maciejwolczyk we’ve been training a neural network that learns how to play NetHack, an old roguelike game, that looks like in the screenshot. Recently, something unexpected happened.
The weirdest bug… is that there was no bug. We just didn’t know how the game worked.
Story of my entire programming life.

Holy hell
Reminds me of this classic: https://unix.stackexchange.com/questions/405783/why-does-man-print-gimme-gimme-gimme-at-0030

There was a speed runner that hit a world record or lost a world record run due to a random bit flip because of space radiation. That’s gotta be worse than just not knowing the deeper mechanics of a very old game.
