Originally posted here: Short translation of the image: Watermill will be built in 29 rounds Current advance: 23,9/360 10 hammers basis 17 hammers total Modifikator for railroad bonus: 50% Modifikator for buildings: 20% You will say now, yes, that's right, 70% more from 10 hammers is 17. But: There are 336 hammers needed to finish the watermill. 336/29 Rounds = 11.58 ~12, which would be if the railroads did not work. Can anyone confirm this? I'll try to get a savegame from this. Edit: Another user is saying that the 29 rounds for finishing the production is shown wrong and that the hammers are applied correctly.
