Been traveling with Piper for quite some time now, but whenever I give her something better than her 10mm pistol, I don't get XP from any kills she makes. It's really annoying since it basically makes the perk "Inspirational" useless, and severely reduces how useful she is in combat.

Check for Piper check detectives office at Diamond City.

She's not missing, I'm just not getting XP for her kills when I give her good weapons.

Nevermind, I'm just not getting xp from half her kills.
