False. SMF was updated within 48 hours of the Freelancer update (Jan 2023) and the Year 3 patches. The original PDP took weeks.
Myth 2: "A better patcher requires reinstalling all my mods."
False. SMF and PDP++ both support original .package files. You do not need to remake mods.
Myth 3: "Better patchers are more likely to get you banned."
False. Hitman 3 has no official online anti-cheat for single-player. All patchers work offline. The game’s online leaderboards are server-sided; using any patcher only affects local assets. Peacock’s redirector is fully offline.
