[.992 Bug] Refined economics research never completes

It is a continuous research.... it never is supposed to be finished, the bonuses just stack. Thus, it should be working as intended, unless your bonuses are not stacking.

This goes for all the refined techs

Wondered about that, myself.  Thanks for the tip.

It should state as much on the Tech screen.  Something to the effect of:

(You can research this tech as often as you wish.  The bonuses received upon completion will stack.)

It says it in the heirganomon

Agreed--but when you're actually on the research screen, an anomaly like this should be pointed out there.  Rather than figuring you might go to the Hiergamenon and run across it.

i was wondering if that might be the case.  thanks.

I've just logged in to check this same issue.   None of the 'refined' research topics appeared to be working....As other's have noted it would help if some note on the research screen indicated the 'repeatable' nature of these fields and also a flag to show if you've already researched one and maybe how many times???

The tech description already says, that they can be researched continuously. The only exception is Refined Agriculture, which is missing that part in the description. Also, in the changelog for 1.20 it is noted, that the tooltip for those techs will state it now, too.
