I can't reproduce this in miniature outside of my document, so I'm asking more debugging help on how I can fix it within the document I have.

The problem is, I have a section with something like:

First is hyperref[P1]Item I, go there. hyperref[P2]Next is item 2, and finally is hyperref[P3]Item III.
newpage

%% later...
section*Item I
labelP1
stuff
section*Item II
labelP2
stuff
section*Item III
labelP3
stuff

Suppose

• Item I, P1 is on page 1.


• Item II, P2 is on page 6.


• Item III, P3 is on page 20.

No matter what I change, hyperref[P3]Item III points to page 5, instead of 20.

I have tried the following debugs:

1. 
   Did I actually mislabel P3 as P2? No, it's P3.


2. 
   Did I actually fail to update the original hyperref, so it still says P2? No, it says P3.


3. 
   Am I sure? How about I call it something totally different, like LOCATION. hyperref[LOCATION]Item III section*Item IIIlabelLOCATION Still points to page 5, not page 20!


4. 
   Is there an error I'm missing, such as: LaTeX Warning: There were undefined references.? Nope, there are no missing references.


5. 
   How about completely remove labelP2 and see if P3 is still pointing there? Removed, yes, it still points to page 5, which now has zero labels intentionally pointing to it.


6. 
   What about debugging the pages themselves? pagerefP1 pagerefP2 pagerefP3 prints 2 7 21 Close enough, but this tells me in fact pagerefP2 is also incorrect. It's not pointing at P2, but at the end of P1, just as P3 is pointing at the end of P1.

Beyond this, I have no idea how to make any refs defined after the first one work, and by that I mean point elsewhere than at page 5. What could be going on?

You need to use

phantomsection
section*<title>
label<label>

since there is no hyper target set with section* like there is with section. If you're only using section* within your document, you could automate this process using

letoldsectionsection % Copy section into oldsection
renewcommandsection%
 phantomsection % Set hyper target
 oldsection*

in your preamble
