While playing Enclave I think I noticed a bug: in my second playthrough (won first as Reformers as well) I have a problem with manpower because the recalculation of manpower after connecting to grid stopped happening.

Previously, when I cored Vault City or Carson City, I was consistently getting the "lump sum" of manpower as a result of core, usually with some decrease in monthly civilian population. Now, when I core 7 provinces at once, including Area 51 (33k manpower strong province), nothing happens in terms of getting additional manpower! The game notices that there is an increase in total manpower from 30.27k to 33.79k, but recruitable population simply changes from 109 to 111.

I did some additional tests and it seems like total hit or miss - some provinces do add lump sum of manpower after connection - Gecko and other VC provinces, whilst other, even with much much bigger manpower (Mountain Home AFB, New Thebes, Mountain City, Area 51 and 6) increase the monthly manpower by 1 or 2, but do not provide any manpower "lump sum" (usually with a decrease in civilian amount) at the end of the month?

I'm still Enclave, getting ready to strike the NCR, with The Fools and Dreamers conscription law. Does this has something to do with the manpower issues I have?

It seems that the coring works only on New Reno, that tribe nation you have reformer focus on, Yakuza and Vault City territories only while I'm playing as an Enclave? Is it because I still didn't conquered the NCR and became USA?

Because I built several grids to connect several large provinces and it was waste of resources :(
