Automech Scrapper persists even if Marisol isn't in the party — i.e. the player will get extra scrap from automechs. This is unrelated to the Scrapper perk that the player can select.

Target body part analysis from N-Ray Scanner Analyzer persists even if Marisol isn't in the party — the game will still display Bleed, Stun & Knockdown (although the effects won't trigger).

I also noticed this bug. Marisol not in party, yet extra loot from the companion perk shows up.
