Researchers Bartłomiej Cupiał and Maciej Wołczyk observed a significant performance drop in their neural network trained to play NetHack. The model, which had been consistently scoring around 5,000 points, suddenly began scoring only 3,000 points, a 40% decrease. Despite extensive troubleshooting, including code reversion, software stack restoration, and rebuilding the entire system from scratch, the performance issue persisted. AI
