I also have almost zero health trying to move on after the advisor section... I've rage quit a couple times. Also, I had the Gnome with me (and some health syringes) when I started that part... but lost them all. Frustrating.

Anyone have any tips or clues for any of these issues?

I haven't finished the Advisor yet. Due to some updates on MOD had to start all the way over and been busy with other stuff. I do remember there is a health module in that room near the ladder. Unless it has been removed. I only found it cause due to corruption after the updates advisor section wasn't working so walked around.

Jeff is a pain, but in the locker room just open a few lockers at a time, then be prepared to RUN. When he leaves open a few more. I think all the ones you need are on the right side. Can't remember due to the stress of the situation. But I have had to go thru it about 3 or 4 times due to problems with the MOD and updates. So just got back today and whipped thru it. Nerve racking, but none the less made it. You can run right past Jeff. Today my biggest problem with him was he wanted to stay near the live grenade dispenser a lot. Finally coaxed him away long enough. He is such a jerk.

Oh, no weapons needed, unless your trying to coax him somewhere. But keep your mouth covered.

To finish him off had to get in the train and shoot off the gun, then run to the elevator when he came over. He was enamored with the live grenade dispenser again. Must have been something with the update.
