I had James Watt with Mausoleum hence +6 prod for factory But another city i conquered very much later after I expended James Watt shows factory has +2 production. Now some of my cities show +9 production from Factory. (6+3 with power, the city has a factory). Now another city Bristol here shows +7 production from nearby factory (bristol doesn't have it's own factory) Now another city Cullen here shows it's getting +5 from nearby factory instead of +9 due to james watt. All of these are from a single turn and am unable to understand why this is happening. Every factory should show +9 production (6+3 with power) and share +9 production with cities in range.
