I just started to use Nick again, and the last time was pre-patch, so I don't know if that is a factor. My Nick makes an annoying click/tick kind of sound constantly is this normal, and did I just not notice it before?

I had this with piper. When I looked up some information, it is apparently a glitch that can't be reversed even with con. commands. The only solution I have found is to go back to a previous save....Hope u save often.

Well in his defense he is a synth, pretty broken down one too. Lol Not sure what Piper's excuse would be. For a second I thought it might be her lighting up a cigarette, but she uses matches.
