Right after I grabbed the anchor I went back up to the pipe factory. The elevator doors open and Lamb walks right in front of me. He won't budge. I'm stuck in a permanent staring contest.

Reloaded over and over. Restarted and played up to this point twice. Clicked all over the place. He's still in my face.

What the heck?

Old post but if anyone else gets the same problem... could try right-clicking on him to talk to him. Whenever I did that Robert would say "Hey lamb" (from wherever he was standing) then Lamb would move into the set position he has for talking to you. I didn't experience this problem myself though, sorry, but just an idea.

When this happened to me, I went back into the elevator. Lamb moves around on a timer, so if you wait a few moments before going back up he should be out of the way.

I got stuck once, but not in that place. It was in the tank room near the end of the game were the android bodies are grown. I click on the door to exit the room but Nurse Joey was on my way and we got stuck into each other. I wasn't able to give any commands (possibly because I was in animation mode), so my only option was to reload. Thankfully I was saving in almost every screen because of fear of sudden death.
