Plumbots loose their trait chips


My plumbot lost all their trait chips


There’s multiple causes for this bug

  • Splitting a household and putting the plumbot to the new family will make them have a last name which they did not have before. This makes them loose their trait chips.
  • ServiceNPCs and homeless plumbots that are put in hibernation loose their trait chips.
  • Reset on older Versions of MasterController, ErrorTrap and Overwatch delete the chips.


  • Make sure to use the newest versions of the mods
  • Don’t invest on putting trait chips into ServiceNPCs and homeless Plumbots
