Is anyone else having the problem where Nick refuses to lockpick anything, even with an abundance of bobby pins? I've heard that he can lockpick up to Expert level, but he won't even lockpick Advanced for me. Note that I've gotten Cait to lockpick some stuff for me so there's no problem there. I've also gotten Nick to hack up to Master level terminals fine so no problem there either.
I've been hearing stuff about the first lock some people asked Nick to pick, he told them to get a key first... I haven't run into a lock with him giving that request yet, so maybe I missed something?
Much thanks for any help offered.

I thought Valentine's specialty was hacking?
