Is my Piper broken?
I'm playing Fallout 4, and I maxed out Affection with Piper, and got her perk. She frequently repeats the last bit that lets me try to choose Romance, but always shoots it down. I have max Charisma (with additional gear boosts), pretty good Luck, and she adores me.
Is it just random, and eventually should work, or did I do something wrong, and it just wants to keep reminding me? I managed it with three other Followers, no problems, but Piper is being uniquely challenging, and I'm not sure if there is a reason. Is it Piper-specific?
It's a known bug:
Cannot romance Piper after she idolizes you (max affinity), even if player character's charisma is maxed. The key/button to select is there, but the option to romance is blank.
Piper seems to be the only one affected by this bug (let's hope it's not contagious).
No fix to be found there, however, nor in this Steam thread, nor this Reddit thread.
This Steam thread has some comments that might prove useful:
All the full affinity followers that I used the just friends option with will initiate a conversation with the option to romance while they are hanging out at Red Rocket. Try swapping companions and travel to wherever you send Piper.
You can trigger the conversation again, by lowering her approval to admire and then raise it again.
