Stop Losing Progress: The FNV Bug Explained
Curiosity spikes as retro games and speedrun tools keep mentioning a classic save-corruption trick. Here is how a tiny math glitch quietly ruins careful grinding.
Stop Losing Progress: The FNV Bug Explained is a well-known ID conflict between item codes and NPC lists in certain engines. This overlap causes items to overwrite saves or crash games unexpectedly. Studies indicate older 32-bit hashes make the issue easier to trigger.
