Weird GNP drop
Ok here's my F9 screenies from 575 BC;550 BC;525 BC. Note the drop in GNP between 575 BC and 550BC. (600 BC preanarchy is a few posts up)
I changed nothing in my city/citizens setting s whatsoever. Very much puzzled. Would the 106 spike have something to do with the free CS tech perhaps? Or is the drop a delayed maintenance issue for bureaucracy. Last assumption isnt supported by the F2 screenie however.
Added a landoverview as well.

EDIT: I just figured out it has to do with the fact I was researching Masonry. If I move my research to another tech the GNP makes the 106-88 drop. First I thought this must be related to the known prequel techs but selecting horse riding also causes the drop but I know all prequel techs for that as well.
Now I'm wondering if this could be related to 'no. of civs that know this tech'. If so that could give a lot of insight in what Rik has been/is researching (basically making researching alphabet even more useless than it is alrdy in a 2 player game) also spikes/drops in Rik's GNP could indicate research switches and tell me if he's researching different techs than I am.
