Whether you’re playing on PlayStation 4 or PC, this guide will help you troubleshoot and fix the most common Fallout 4 bugs, so you can get back to exploring the Commonwealth.

1. Floating or Stuck NPCs

Issue:

NPCs get stuck in place, float in the air, or refuse to move, making quests and interactions impossible.

2. Items Disappearing from Inventory or World

Issue:

Weapons, armor, or quest items vanish without explanation.

Fixes for PS4:

  • Check Companion Inventory: Companions sometimes auto-equip or store items.
  • Reload an Earlier Save: If the item recently disappeared, load a previous save.
  • Rebuild Settlements: If workshop items disappear, enter build mode and try re-placing structures.

Fixes for PC:

Issue:

A quest fails to trigger, NPCs don’t recognize completed objectives, or markers won’t update.

Fixes for PS4:

4. Game Crashes or Freezing

Issue:

Random crashes to the home screen or the game freezing mid-play.

Fixes for PS4:

  • Clear System Cache: Restart your console and hold the power button until it fully shuts down.
  • Reduce Save File Size: Large saves can cause crashes. Delete old saves and limit settlement building.
  • Disable Mods: If using mods, disable them one by one to identify the cause.

Fixes for PC:
