To complete your merge outfit in Crooked Cop after transferring components when you cannot add an accessory:
Open Interaction Menu and change the Racing Outfit Quit the job through your phone as normal. Note: You can also complete the job to avoid Bad Sport. Load back into a GTA Online Session and start any Rockstar Created Job > Mission (A Titan of A Job, Chopper Tail, etc). Load into the job alone and you will see your merge outfit from Crooked Cop: Save the outfit at any Ammunation, CEO Building, or Apartment and quit/complete the job. You will load back into the session with your saved merge outfit.
This may be useful when you don’t want to lose your hat/helmet, are wearing checkered items, don’t have rebreather/ear piece, or unable to change accessories in your Interaction Menu.
