Sometimes on restart your Assaultron will have an annoying red beam of light coming from it's head, a sparkling orb at it's feet, or a Mr Handy thruster flame between their legs!

This is due to bugs in scripts supplied in the Unofficial Fallout 4 Patch (UFO4P) Mod interacting with the Robot Workbench.
When a fix for this issue is officially released in a future UFO4P update this mod will no longer be required.

UPDATE: This fix has now been included in Community Fixes Merged. You do not need my fix if you use the latest version of CFM (2.5.3 or later).

This mod supplies a note that, when read/added to your inventory, will remove any existing stuck effects on all nearby Automatrons
(and all Companion Automatrons).
This mod also supplies fixed versions of the UFO4P scripts to prevent the issue in the future.
(There is an optional download with just these fixes - all you need if the problem has not yet occured to you - or use CFM)

After picking up and saving the note, a message will be displayed detailing the number of nearby Robots checked/fixed so you know it worked.
The problem will then not return when you next resume your game.

It does not remove the effects entirely (like the other fix mods do) - it just removes them only when they shouldn't be there so Sentrybot heads will still have the light, and Protectron Shock Claws will still have the lightning orb effect. This mod fixes the bug, but does not change the game.

The note will be found on the Workshop Workbench in the RedRocket near Sanctuary
and can be saved for future use. If you have heavily modified RedRocket and can't find the note, then bring it to you via the console command "xxxxx802.moveto player" (where xxxxx is the ID of this mod in your load list).

To re-apply the effect you need to drop the note and pick it up again.

You can add and remove this mod at any time and it will not effect your game or saves, However you will loose the fixes that prevents it happening again (unless you use CFM 2.5.3 or later).

Install either the loose files or Archive version of this mod NOT BOTH.

Conflicts & Requirements:
This mod won't conflict with any other mods.
It also has no DLC dependencies, but is quite pointless if you don't have Automatron DLC.
It is an ESL so does not take up a mod slot.
Note: The "loose files" version requires bInvalidateOlderFiles=1 (under [archive] in your Fallout4Custom.ini or Fallout4.ini) to be set.

Did not fix your problem?
Unfortunately the 'stuck effects' can sometimes compound (become very bright) but this mod can only remove one instance of the effect.
In that case your only option is one of the other mods that remove the visual effect entirely. Sorry.

Problem Details:
This is a bug that can occur when you use the robot workbench and scroll past the Sentrybot head, Protectron shock claw, or Mr Handy Thruster mods - even though you don't actually choose them for your Automatron. All appears fine until you restart (resume) your game, when these effects mysteriously appear on the Companion Automatron you last worked on (including Ada).
The visual effects are enabled via a script when you highlight the appropriate mod (e.g. Sentrybot head), and removed when you move to the next option, however on slow systems (or with a lot of script lag - say from SS2) they would not be removed in time and remembered as "on".
On the next restart the game enables them (as it thinks they were on when you saved).
This mod fixes those scripts, as well as manually turns the effects off again (when you read the note) - which is remembered in your next save.
