hugo server mode. 0.37.1only every 2 changes . So I need to save twice to see my change on the browser.
As I never had this behaviour, I was reluctant to post this report, but as I can reproduce it, well …
I can reproduce like that with a fresh hugo:
I have a test string on the page : test 1
 
Start hugo server --ignoreCache --gc to avoid any cache problem. 
look my result on the browser : test 1. 
change the string to test 2 => I see hugo rebuilding site  on the console. 
look my result on the refreshed  browser ==> still test 1  !!! even If i clear browser cache in chrome developper mode … 
I stop hugo on the console. 
Start again hugo server --ignoreCache --gc. And I do nothing on my file. 
I just refresh the browser and now  I can see test 2 as expected. 
 
[ PS : I suspect this is maybe related with my code using getCSV because I started to see those pb when I was trying to use CSV files in /data/ folder. I no longer use csv in /data/ and I changed for a standard /csv/ folder.original post ] 
And doing --debug & --verbose doesn’t produce any différence I can see.
Sorry the repo is not publicly available, but I can send a zip if needed.
             
            
              
            
           
          
            
            
              Only difference I can notice is that the wrong build take ~50% time of the right build !

It doesn’t cover your issue, I think – but I somehow borked parts of the reload logic. It is an area where we lack some automatic testing … I will issue a patch release fairly soon.
             
            
              
            
           
          
            
            
              Thanks @bep .
Yes it is not exactly the same cause, but the logic behind is similar : no refresh when a page is updated from local content (CSV in my case & not in /data/ folder).
I will test your patch/0.38.1 when they are out and let you know if it solves this specific trouble.

Let me know if you want me to test something else.
