First, clarity is critical. If you search for "Fallout 4 1.10.163" on Steam or Nexus Mods, you will find two distinct realities:
You can manually download the older files directly from Steam's servers:
Stay safe out there, Vault Dweller. And remember: War never changes, but Bethesda patch numbers do. Check your F4SE version before clicking "Update All."
Closing note 1.10.163 is a compact example of how small official updates interact with a complex mod ecosystem: technically minor for the base game, but operationally meaningful for mod users and developers.
Because 1.10.163 offered no tangible benefits to mod users but broke F4SE, many in the modding community immediately created downgraders (e.g., the "Fallout 4 Downgrader" on Nexus Mods) to revert to 1.10.162. Bethesda did not comment on this, but the patch was widely seen as a necessary evil to prepare servers for the much larger next-gen update that followed a month later.
The consensus: If you have a stable mod list, freeze your game version now via Steam’s "Beta" tab (password: backupMyMods123 – Bethesda’s official rollback branch). Only update if you play vanilla or only use texture/asset mods that don't require F4SE.
