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.

    Their problem:

    So apparently NetHack has a mechanic that slightly changes how the game plays every time it’s full moon according to your system clock

    The model wasn’t trained on a full moon. They had a system to set up the environment for replicable results but it didn’t include modifying the system time.
