Fuse insertion will not respond

Match the symptom

The developer improved fuse insertion in Update 6; the note does not specify a universal cause for every failed insertion.

Check before changing your save

Check whether the fuse can be selected, whether the target offers an insertion prompt and whether the object actually enters the slot. If insertion works but the objective stays incomplete, record that as a recognition problem instead.

1. Confirm Steam has completed all available updates.
2. Check whether the fuse can be selected, whether the target offers an insertion prompt and whether the object actually enters the slot. If insertion works but the objective stays incomplete, record that as a recognition problem instead.
3. Keep a save before the electrical interaction. Do not buy repeated fuses or dismantle working connections merely to test an inactive prompt. This is game-only troubleshooting.

Official fix versus your current save

The developer's Update 6 note establishes a historical fix for this symptom. It does not publish a universal recovery command or prove that a previously damaged save will repair itself. This guide has not independently retested your save.

Recovery decision

Keep a save before the electrical interaction. Do not buy repeated fuses or dismantle working connections merely to test an inactive prompt. This is game-only troubleshooting.

1. If the installed game is older than the named patch, update and retest the same action.
2. If the issue persists, try an existing known-good save without overwriting the failing one.
3. If it repeats, report fuses, the exact objective, installed build and reproduction steps to the developer's Steam discussion board.
