Hello Everybody! Recently i have found some time to play (with editor of) this wonderful game due all world events that took place since start of this year. One box under Improvements section made me wondering about consenquences it might produce - it is “Replaces all Impr. with this flag”. I am familiar with it’s power plants function, aswell as it’s use for City Attributes in Worldwide mode. But I could not find answer for this, even though I tried to Google it, search via search function on this forum and via manually opening threads. Let me try to explain (English is not my main language so i apologise) - What if “Improvement-A” and “Improvement-B” have this flag checked. Bear with me, it is not that simple haha. Now, there is “Improvement-A2” which has prerequisite of “Improvement-A”. There is also “Improvement-B2” that has prerequisite of “Improvement-B”. Please, take a note that Improvement-A2 and Improvement-B2 DO NOT have “Replaces all Impr. with this flag” checked, just it’s prerequisites. To eliminate this out of equation - both of this first type (A and B) improvements have “1 production” (25%) bonus checked to make sure AI builds it - due known bug about “Replaces all Impr. with this flag“ without prodction bonus. Now my question is - If Player/AI builds “Improvement-A” and “Improvement-A1” but then decides to build “Improvement-B” - will “Improvement-A1” still function as before (for example- still producing units or providing it’s bonuses)? I tried looking via Debug mode, but only thing I can see is that all 3 improvements are still in City, but can not see do they function. If You have read all this and did not understand me, let me bog it down to it’s simpliest form. There are Temple and Market marked with “Replaces all Impr. with this flag“. If Player/AI builds Temple and then Cathedral which needs Temple first, and then decides to build Market - will Cathedral bonus still work even though Temple is replaced? Thank You for reading and further input.
