The new technology make a bonus of +8% production in new building near identical others, but don´t work in building of the same type previously builded, even before the technology was developed and after that.
For example:
One build 1 stable after the technology, and after that you build another stable, and other. The 1st stable get 1 bonus, the other 2nd get 2 bonus cummulative (+16%), and the 3rd 3x bonuses (+24%)
Please correct this.
